[0002] Creating weather phenomena for game scenes is a common function in game engines. These weather phenomena include rain, snow, lightning, rainbows, etc. In related technologies, weather phenomena can be created manually by artists, but this method requires artists to manually create weather blueprints and manually modify the scene materials corresponding to the weather, making the manual production process cumbersome and the logic used in the game complex, requiring a lot of manpower.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0038] Creating weather phenomena for game scenes is a common feature in game engines. These weather phenomena include rain, snow, lightning, rainbows, etc. In related technologies, weather phenomena can be created manually by artists. When manually creating weather phenomena, the following preparations are required:

[0039] 1. It is necessary to produce the required resources such as models, materials, textures, special effects, and blueprint logic. The production process is cumbersome and cannot be quickly built into the game scene. Some weather effect combinations cannot achieve the desired effect. The linkage between weather effects is not strong, making production difficult and prone to errors. It has a large reliance on the logical implementation of the client program, takes a long time to debug, and the effect is not ideal.

[0040] 2. Use particle effects to create weather phenomena, and then manually modify the PBR (also known as specular reflection / gloss) properties of the material to create the surface effects of virtual objects affected by the weather. For example, the surface of an object wetted by precipitation and the accumulation of snow on an object require manual design of the Shader (equivalent to a shader) connection of the PBR material node in the Material Editor (the Material Editor is used to describe the vertex data and triangle indicators of a 3D model). This process is completely manual and time-consuming. If there are many objects and many materials, it will take many people and days to set the materials of different objects. This is inefficient, and if multiple people are involved in editing, the time and effect cannot be guaranteed, and it is difficult to achieve a satisfactory effect, which also wastes man-days. Among them, PBR material is a physically based rendering material that can provide an accurate representation of how light interacts with surfaces; man-days refers to the amount of work completed by one person in a day.

[0041] 3. Create weather objects. For example, creating weather objects such as rain, snow, and lightning is a tedious manual process and requires complex logic to use in games.

[0042] Therefore, manually creating weather phenomena by artists is a tedious process, with complex logic required for in-game use, and requires significant manpower. Furthermore, current game engines lack direct functionality for weather phenomena, forcing users to create them manually (equivalent to the manual implementation mentioned above) or through plugins. Related technologies include the Dynamic_Weather and Good Rain weather plugins.

[0043] However, the Dynamic_Weather plug-in can only implement each individual weather phenomenon in the form of a blueprint, and there is no overall tool to integrate it. Others who want to use it can only copy its project to modify the materials and blueprints inside, which does not effectively solve the production efficiency and production quality issues in the production. In addition, there is no correlation between weather phenomena, such as snow, rain, and other individual weather phenomena. At the same time, the plug-in does not have a unified operation interface, and needs to be manually called up in the resource bar and various nodes added in the blueprint editor. This also requires knowledge of weather blueprint production, which is complicated to operate. In addition, this method has no unified material conversion function. When making objects affected by weather phenomena such as rain and snow, it is necessary to manually change the node connections in the object's material ball one by one. The whole process is very cumbersome and requires knowledge of weather material production.

[0044] The GoodRain weather plug-in only implements a raining solution, and the effect achieved is relatively simple. It can be barely used if it only deals with rainy days, but it cannot achieve complex linked weather changes (such as instantaneous changes in various weather conditions, transitioning from rainy days to snowy days, controlling weather changes in time, controlling weather changes in space, interaction with the water surface, and other complex transformation effects).

[0045] In summary, creating weather phenomena in game engines is a lengthy process, and quality is unpredictable. Even for experienced users, Blueprint's built-in connection logic is complex, the effects are limited, and inefficiency is a common problem. Different software programs have varying requirements for weather effects, and within the current limits of what can be achieved, creating a perfect weather effect remains difficult.

[0046] Based on the above problems, the embodiments of the present invention provide a method, device and electronic device for generating weather effects in a virtual scene. The technology can be applied to the scene of adding weather effects to the game scene. In order to facilitate the understanding of the embodiments of the present invention, the method for generating weather effects in a virtual scene provided by the embodiments of the present invention is first introduced in detail. The method is applied to a game engine with a weather plug-in installed. The weather plug-in can automatically generate weather effects in the virtual scene (the weather effect can also be understood as the effect of a certain weather phenomenon); Figure 1 As shown, the method includes the following specific steps:

[0047] Step S102, obtaining a selected target weather object; the target weather object is included in a plurality of preset weather objects; the weather object is used to achieve a corresponding weather effect; the weather object includes material information and / or grid information for achieving the corresponding weather effect.

[0048] During implementation, developers pre-set multiple weather objects (also called weather objects) in the weather plugin. These objects can include lightning, rain, thunderstorms, hail, dust, sandstorms, rainbows, auroras, snow, and more. The specific preset weather objects are determined by development requirements. Each weather object corresponds to a corresponding weather effect. For example, the weather effect for rain is rainfall, and the weather effect for snow is snowfall.

[0049] Each weather object includes material information and / or mesh information used to implement its corresponding weather effect. Specifically, a weather object may correspond to only material information, only mesh information, or both. Material information indicates the material properties of the weather object and the material properties of the model in the virtual scene under the weather effect corresponding to the weather object. Mesh information indicates the shape and size of the weather object, as well as the shape of the weather effect corresponding to the weather object.

[0050] Step S104, based on the target weather object, update the attribute information in the preset weather blueprint framework to obtain the target weather blueprint corresponding to the target weather object, which is used to indicate the generation time and generation location of the target weather effect corresponding to the target weather object in the virtual scene.

[0051] The aforementioned weather blueprint framework is a universal framework required for generating any type of weather effect. This universal framework contains preset weather-related attribute information, which includes multiple attributes and default values ​​for each attribute. The attribute information may include attributes such as wind speed, temperature, humidity, and fog effects. In a specific implementation, after acquiring a target weather object, the material information of the target weather object is automatically identified. Then, based on the material information of the target weather object, the attribute information in the weather blueprint framework is updated, thereby determining the updated weather blueprint framework as the target weather blueprint corresponding to the target weather object. This target weather blueprint contains the logic for achieving the target weather effect for the target weather object, as well as the generation time and location for generating the target weather effect in the virtual scene.

[0052] The above generation time and generation location can be adjusted according to user needs, or default values ​​can be used. For example, the time for generating the target weather effect in the virtual scene can be noon, and the generation location can be the location of the virtual character or the entire virtual scene.

[0053] It's important to note that the game scene (equivalent to the aforementioned virtual scene) built by a game engine consists of a node network used to construct game logic and models (these models can be referred to as objects within the game scene). A blueprint is typically a special type of asset within a game engine. Blueprints can create logic and set variable data, such as material and mesh information, in an intuitive, node-based manner. In other words, blueprints are primarily used to construct game logic and objects.

[0054] Step S106: generating a target weather effect in the virtual scene based on the target weather blueprint.

[0055] In a specific implementation, a target weather effect corresponding to a target weather object can be automatically generated in a virtual scene according to the logic of the target weather blueprint. Specifically, the material properties of objects in the virtual scene can be adjusted according to the material information or object characteristics (such as the humidity and shape of the weather object) of the target weather object corresponding to the target weather blueprint, so that the material properties of the objects match the target weather effect corresponding to the target weather object, thereby displaying the virtual scene under the target weather effect.

[0056] In actual applications, a graphical user interface is provided by a terminal device, in which multiple controls in a weather plug-in for generating weather effects in a virtual scene are displayed; therefore, in response to a trigger operation on a weather generation control, a weather blueprint framework is obtained; then, in response to a selection operation of a target weather object from a plurality of preset weather objects, the selected target weather object can be obtained, and based on the target weather object, the attribute information in the weather blueprint framework is updated to obtain a target weather blueprint corresponding to the target weather object; wherein, one weather object corresponds to one selectable control; in response to a trigger operation on an effect conversion control, a target weather effect is generated in the virtual scene based on the target weather blueprint.

[0057] Specifically, the weather object creation control displays multiple preset weather objects. The user can select one of these weather objects as the selected target weather object, allowing the game engine to retrieve the target weather object. Specifically, the user can click the desired weather object in the weather object creation control with the mouse, and use the clicked weather object as the target weather object. For example, if the user wants to generate a rainy weather effect in the virtual scene, they need to click the rain object in the weather object creation control with the mouse; if the user wants to generate a snowy weather effect in the virtual scene, they need to click the snow object in the weather object creation control with the mouse.

[0058] An embodiment of the present invention provides a method for generating weather effects in a virtual scene. The method first obtains a selected target weather object, which is included in multiple preset weather objects and is used to achieve a corresponding weather effect. Based on the target weather object, the method updates the attribute information in a preset weather blueprint framework to obtain a target weather blueprint corresponding to the target weather object. The target weather blueprint indicates the generation time and generation location of the target weather effect corresponding to the target weather object in the virtual scene. The method then generates the target weather effect in the virtual scene based on the target weather blueprint. This method selects the target weather object from multiple pre-set weather objects, saving time in creating the weather object. The method then displays the target weather effect corresponding to the target weather object in the virtual scene based on the weather blueprint corresponding to the target weather object. This method is automated, saves manpower, and improves the efficiency of achieving weather effects in the virtual scene.

[0059] The embodiment of the present invention also provides another method for generating weather effects in a virtual scene. This method is implemented on the basis of the above embodiment. The method focuses on describing the specific process of updating the attribute information in the preset weather blueprint framework based on the target weather object to obtain the target weather blueprint corresponding to the target weather object (specifically implemented by the following steps S206-S208), and the specific process of generating the target weather effect in the virtual scene based on the target weather blueprint (implemented by the following step S210); Figure 2 As shown, the method includes the following specific steps:

[0060] Step S202: Generate a weather blueprint framework containing attribute information; wherein the attribute information includes at least one of wind force, temperature, humidity, and fog effect; and all attributes in the attribute information are set to default values.

[0061] In practice, the game engine's graphical user interface for the weather plugin displays a framework generation control. Clicking this control instantly generates a weather blueprint framework containing attributes for key functions like wind speed, temperature, humidity, and fog effects. Within the weather blueprint framework, the attribute values ​​are all default values ​​designed by the developer, which can be adjusted or not.

[0062] Step S204, obtaining a selected target weather object; the target weather object is included in a plurality of preset weather objects, and the weather object is used to achieve a corresponding weather effect.

[0063] In a specific implementation, the target weather object is selected by the user from a plurality of pre-set weather objects, wherein each of the plurality of pre-set weather objects can be constructed by the following steps 10-13:

[0064] Step 10: Form an initial object by stacking mesh faces.

[0065] The initial object is formed by stacking single mesh patches, such as Figure 3 The following is a schematic diagram of the production of the rain object. Figure 3 The left side of the figure shows the effect of stacking multiple meshes. Each single piece corresponds to a mesh. By converting the stacked meshes, a Figure 3 The right side shows the rain object. Furthermore, each mesh in this initial object uses only one material. Compared to existing methods of creating weather objects using particle effects, this initial object creation method does not require particle system initialization time, thus improving object creation efficiency.

[0066] The stacking effect of these meshes can also be understood as the initial state of the weather object (equivalent to the initial object), which is usually invisible. Because the stacking effect is calculated in the vertex shader, this production method has almost no CPU (Central Processing Unit) computational cost and runs extremely fast.

[0067] Step 11: Obtain vertex data of the initial object; wherein the vertex data includes coordinate positions of multiple vertices of the initial object.

[0068] Step 12: Based on the vertex data, coordinate transformation is performed on the initial object to obtain an intermediate object facing the camera.

[0069] In actual implementation, the GPU (Graphics Processing Unit) indexes the vertices of the initial object to obtain vertex data. At this point, the stacked mesh faces and the final weather object seen on the screen are in two different coordinate systems. A coordinate transformation is then required. This is done by finding the transformed coordinate system of the two coordinate systems. Based on this transformed coordinate system, a matrix transformation is then applied to the mesh faces, ultimately transforming them into a long, rectangular object. The transformed object then undergoes another conversion to world space, with the corner faces of the rectangular object oriented towards the camera, becoming a billboard object (equivalent to the intermediate object).

[0070] In order to facilitate the understanding of the coordinate transformation of the initial object, such as Figure 4 The figure shows a schematic diagram of coordinate transformation of an initial object; Figure 4 The three cylinders in the figure can identify the initial object, the observation point e represents the camera position, and the target point t is also calculated as a triangular face on the initial object. The heading vector is used to indicate the direction of the target point in the coordinate system of the object. By transforming the heading vector to the world coordinate system, we can get the intermediate object facing the camera.

[0071] Step 13: Set the attribute information of the intermediate object to obtain the weather object.

[0072] The attribute information here can include the material properties of the weather object, the falling speed, the falling trajectory, or other properties. For example, when creating a rain object, the initial rain particles are formed when the billboard object is transformed. Then, by performing a positioning operation on the patch and moving it downward according to the preset speed and direction, the falling motion trajectory can be achieved. Then, based on the set weather object, different textures and transparent maps are assigned to the materials, and fusion and transition are set on the materials to initially generate the rain object.

[0073] Step S206: Update the attribute information in the weather blueprint framework to attribute information that matches the target weather effect corresponding to the target weather object.

[0074] Since different weather effects correspond to different attribute information, and the attribute information corresponding to each weather effect is pre-set and can be arbitrarily set according to user needs, in specific implementation, after the user selects the target weather object, the attribute information in the weather blueprint framework can be updated with the attribute information of the target weather effect corresponding to the target weather object.

[0075] Step S208: The weather blueprint framework after the attribute information is updated is determined as the target weather blueprint. The target weather blueprint is used to indicate the generation time and generation position of the target weather effect corresponding to the target weather object in the virtual scene.

[0076] Step S210 , based on the target weather blueprint, adjusting the material properties of the specified model in the virtual scene, obtaining the display state of the specified model under the target weather effect, and displaying the specified model in the virtual scene based on the display state.

[0077] In a specific implementation, the material properties of a designated model in the virtual scene can be adjusted based on the material information or object characteristics (such as the humidity and shape of the weather object) of the target weather blueprint. The designated model is the object in the virtual scene whose material properties need to be modified. The object can be a scene, a building, or the ground in the virtual scene. In actual applications, the objects in the virtual scene can be pre-set as designated models, or the designated models whose material properties need to be modified can be automatically identified among the objects contained in the virtual scene.

[0078] The material properties of the specified model in the virtual scene will be adjusted according to the current target weather effect, so that the material properties of the specified model match the target weather effect corresponding to the target weather object, so that the virtual scene can be displayed under the target weather effect.

[0079] Step S212, generating a screen post-processing effect of a virtual lens for shooting a virtual scene based on the material information corresponding to the target weather object; wherein the screen processing effect matches the target weather effect, and the screen post-processing effect includes: one of: a frozen screen, a wet screen, or a heat-distorted screen.

[0080] In specific implementation, screen post-processing can be dynamically generated based on the material information corresponding to the target weather object, which is used to distort the original virtual lens screen to achieve the effect of the lens being wet, frozen, and twisted by hot air, which more realistically shows the target weather effect. In actual applications, the implementation method of screen post-processing is to connect the material nodes of the virtual screen through pre-made nodes, automatically generate normal maps for raindrops and ice, and then generate post-processing effects (equivalent to screen post-processing effects) through Post Process Volume (referred to as post-processing box). Figure 5 FIG. 1 is a schematic diagram of a screen post-processing effect provided by an embodiment of the present invention. Figure 5 The screen lens is shown as wet.

[0081] Specifically, the graphical user interface provided by the game engine for the weather plug-in displays a control for quickly setting the player character's weather post-processing effects. Clicking this control quickly generates screen post-processing effects based on the target weather effect (which can also be understood as one-click generation). In actual implementation, the above-mentioned screen wetting effect is specifically achieved by determining the position and flow direction of raindrops through word normal, and generating the wetting effect of falling raindrops based on the determination result; the above-mentioned screen heat distortion effect can be achieved by perturbing the virtual screen with a noise map; and the above-mentioned screen icing can be achieved through the ice crack normal-screen-sticking method.

[0082] The above-mentioned method for generating weather effects in virtual scenes utilizes a fully automated process and advanced weather object setting effects, effectively improving production efficiency. This method is characterized by fast production speed, high-quality generated weather effects, ease of implementation, extremely low memory usage, and good optimization performance. At the same time, this technology will not have any performance issues when used in mobile game production.

[0083] The embodiment of the present invention also provides another method for generating weather effects in a virtual scene. This method is implemented on the basis of the above embodiment. The method focuses on the specific process of adjusting the material properties of a specified model in the virtual scene based on the target weather blueprint, obtaining the display state of the specified model under the target weather effect, and displaying the specified model in the virtual scene based on the display state (specifically implemented through the following steps S508-S512); Figure 6 As shown, the method includes the following specific steps:

[0084] Step S502: Generate a weather blueprint framework containing attribute information; wherein the attribute information includes wind speed, temperature, humidity and fog effect.

[0085] Step S504, obtaining a selected target weather object; the target weather object is included in a plurality of preset weather objects, and the weather object is used to achieve a corresponding weather effect.

[0086] The preset multiple weather objects are set in advance by the R&D personnel, and each weather object can achieve the corresponding weather effect. Figure 7 FIG. 1 is a schematic diagram of a weather object creation control provided by an embodiment of the present invention. The weather creation control (the weather creation control is equivalent to the class selection control corresponding to the above-mentioned weather object) includes 9 preset weather objects.

Users can click Figure 6Click the icon corresponding to any weather object shown to select the weather object.

[0087] Figure 7 The second line in the display has "Follow seletion object's position to create", Figure 7 By checking the box in front of the display area, you can generate a weather object based on the coordinates of the selected object (the object is usually an object in the virtual object).

[0088] After the user selects the target weather object, the user can click the control that lists weather objects corresponding to the weather plug-in, and then a list of target weather objects selected by the user will be displayed in the graphical user interface. Clicking the list can also modify the information in the list. The information in the list includes attribute information, etc., which is set according to R&D needs.

[0089] Step S506, based on the target weather object, update the attribute information in the preset weather blueprint framework to obtain the target weather blueprint corresponding to the target weather object, and the target weather blueprint is used to indicate the generation time and generation location of the target weather effect corresponding to the target weather object in the virtual scene.

[0090] In some embodiments, in response to a modification operation on the generation time and / or generation location indicated by the target weather blueprint, a target weather effect can be generated in the virtual scene based on the modification result. Specifically, the generation time and generation location of the target weather effect in the virtual scene can be manually modified or adjusted by the user, thereby increasing the fun of the game.

[0091] Step S508: identifying a designated model in the virtual scene whose material properties need to be adjusted.

[0092] In specific implementation, the objects in the virtual scene that currently need to adjust the material properties can be automatically identified and the objects that need to adjust the material properties can be determined as designated models; or the user can select the objects in the virtual scene that need to adjust the material properties.

[0093] Step S510: Based on the material information corresponding to the target weather in the target weather blueprint, the material properties of the specified model are adjusted to obtain the display state of the specified model under the target weather effect.

[0094] In a specific implementation, the material information corresponding to the target weather object may include the material properties that need to be adjusted for the specified model. This allows the material properties of the specified model to be directly adjusted to a combination of the material properties included in the material information and the original material properties of the specified model, thereby making the weather effects presented in the virtual scene more realistic. In some embodiments, a material may be selected based on the target weather effect corresponding to the target weather object, and then the material properties of the specified model may be overlaid on the selected material.

[0095] In practical applications, the above step S510 can be implemented through the following steps 20-22:

[0096] Step 20: Scan the material properties of the specified model to obtain the material setting node of the specified model.

[0097] Step 21: Automatically connect the material setting node of the target weather object with the material setting node of the specified model.

[0098] Step 22, through the connection relationship of the material setting node, the material properties of the specified model are superimposed on the material properties indicated by the material information corresponding to the target weather object to obtain the display state of the specified model under the target weather effect.

[0099] In a specific implementation, this method dynamically sets a material system through programming. This material system can scan the original material properties of objects in the virtual scene, analyze the data structure of the material properties, and then determine the location of the object's material setting node. The preset weather object's material setting node is then automatically connected to the object's material setting node. At this time, the function of the object's material setting node will become the function of the weather object's material setting node, which means that the node structure in the material system is changed, so that the object's material can be set through the weather object's material setting node. Therefore, the present invention can set the material properties required by any weather object for objects in the virtual scene.

[0100] In actual applications, the graphical user interface provided by the game engine for the weather plug-in displays a control for converting materials to weather materials. The user clicks the control to adjust the material properties of the specified model to the material properties corresponding to the selected weather object, or to the selected material properties.

[0101] In the specific implementation, the above-mentioned weather control also has the function of batch conversion of materials: select the root material file that needs to be changed, and press the control to convert the material into a weather material to automatically convert the material into a weather material. The material will show the appearance of being wet, snowy, and sandy, and will not destroy the original function of the material.

[0102] In some embodiments, the material properties of the specified model after the material properties are adjusted can be replaced with the material properties of the specified model before the material properties are adjusted, according to the original material conversion instruction. Specifically, the graphical user interface also displays a control for restoring the weather material to a normal material. The user clicks this control to send the original material conversion instruction, thereby replacing the adjusted material properties of the specified model (equivalent to the weather material) with the normal material (equivalent to the original material of the specified object).

[0103] Step S512: displaying the designated model in the virtual scene based on the display state.

[0104] Step S514: generating a screen post-processing effect of a virtual lens for shooting a virtual scene according to the material information corresponding to the target weather object; wherein the screen processing effect matches the target weather effect.

Specifically, the occluder creation control provided in the graphical user interface can be clicked to automatically add occluders to the scene models in the virtual scene.

[0106] In a specific implementation, the weather plug-in provided by an embodiment of the present invention also includes a quick settings panel that displays stacked settings controls. In response to a triggering operation (which may be a click operation on the controls) of the stacked settings controls, a quick preview of the humidity and snow cover of the model surface in the virtual scene can be provided. The quick settings panel also displays a wind speed setting control. In response to a triggering operation of the wind speed setting control, a quick setting of the wind vector direction can be provided.

[0107] In actual application, in response to the operation of dragging the virtual character to the designated location in the virtual scene generating the target weather effect, the virtual character is set at the designated location. Specifically, the quick setting panel is also provided with a character setting control, which can be triggered to drag the designated character to the designated location in the virtual scene.

[0108] In some embodiments, the target weather can be generated in the area where the avatar is located in response to the operation of modifying the generation location of the target weather blueprint to the area where the avatar is located. This method can increase the fun of the game and help improve the player's gaming experience.
