[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] First, the nouns involved in this application are introduced:

[0029] (1) Virtual scene (game scene)

[0030] A virtual scene is a virtual scene displayed (or provided) when an application is running on a terminal or server. Optionally, the virtual scene is a simulation environment of the real world, or a semi-simulation and semi-fictitious virtual environment, or a purely fictitious virtual environment. The virtual scene is any one of a two-dimensional virtual scene, a 2.5-dimensional virtual scene, and a three-dimensional virtual scene. The virtual environment can be the sky, land, ocean, etc., wherein the land includes environmental elements such as deserts and cities. Among them, the virtual scene is a scene with complete game logic of virtual objects such as user control. For example, for sandbox 3D shooting games, the virtual scene is a 3D game world for players to control virtual objects to fight. Example virtual scenes may include: at least one element of mountains, plains, rivers, lakes, oceans, deserts, skies, plants, buildings, and vehicles; for example, for 2D or 2.5D card games, the virtual scene is a scene for displaying released cards or displaying virtual objects corresponding to cards. Example virtual scenes may include: an arena, a decisive battlefield, or other "field" elements or other elements that can display the status of card battles; for 2D or 2.5D multiplayer online tactical competitive games, the virtual scene is a 2D or 2.5D terrain scene for virtual objects to fight. Example virtual scenes may include: canyon-style mountains, lines, rivers, classrooms, tables and chairs, podiums and other elements.

[0031] (2) Virtual Objects

[0032] A virtual object refers to a dynamic object that can be controlled in a virtual scene. Optionally, the dynamic object can be a virtual character, a virtual animal, an animated character, etc. The virtual object is a character controlled by a player through an input device, or an artificial intelligence (AI) set in a virtual environment battle through training, or a non-player character (NPC) set in a virtual scene battle. Optionally, the virtual object is a virtual object that presents special effects in a virtual scene. Optionally, the number of virtual objects in the virtual scene battle is preset, or is dynamically determined according to the number of clients joining the battle, and the embodiment of the present application does not limit this. In a possible implementation, the user can control the virtual object to move in the virtual scene, for example, control the virtual object to run, jump, crawl, etc., and can also control the virtual object to fight with other virtual objects using skills, virtual props, etc. provided by the application. In this embodiment, after the virtual object is loaded in the virtual environment, the pre-set special effects can be presented on the virtual object.

[0033] At present, special effect particles are usually produced in the form of special effect particle tailing. The tailing special effect (also called ribbon special effect) is a type of special effect particle, which is usually used to achieve the effect of fast movement of objects. The effect, length and color of the tailing can be controlled. Common special effects include bullet tailing, knife light tailing, etc. The tailing particle is actually the movement trajectory led by the front particle, that is, it is not the ribbon that drives the movement, but the ribbon head keeps generating the nodes of the ribbon particles.

[0034] At present, the method of presenting special effects in virtual scenes is to use special effect particle trailing to produce them. For example, in a game scene, when a player controls a virtual gun to fire bullets through attack operations, a bullet trailing special effect will be displayed in the game scene, or when a player attacks an enemy, by waving a knife, a knife light special effect will be displayed in the game scene, or a meteor shower effect will be presented in the virtual sky through special effect particle trailing, etc. However, the special effects currently generated by using special effect particle trailing cannot be applied to virtual characters with materials, which will separate the displayed special effects from the virtual characters, resulting in poor special effect display effects.

[0035] Based on this, the embodiments of the present invention provide a special effects processing method, device, terminal device and computer-readable storage medium, which can generate a target special effects image with relatively realistic special effects, and can obtain a virtual object that displays real special effects, thereby avoiding the separation of special effects and virtual objects and improving the display effect of special effects on virtual objects.

[0036] To facilitate understanding of this embodiment, the present invention provides a special effect processing method, which provides a graphical user interface through a terminal, and the content displayed by the graphical user interface includes at least a virtual object. To facilitate understanding, a special effect processing method disclosed in an embodiment of the present invention is first described in detail. Figure 1 As shown, the method comprises the following steps:

[0037] Step S102, obtaining an object map of a virtual object to which special effects are to be added.

[0038] The object map may include an object map that has been rendered for a character, or may include an object map that has not been rendered originally. If the object map that has been rendered for a character is obtained, there is no need to further process the object map. If the original object map, such as an albedo map, is obtained, the albedo map (i.e., the original object map) may be used for character rendering by a rendering tool.

[0039] The object map rendered in this embodiment is an object map containing the character material.

[0040] Step S104, collecting the special effect particle area in the pre-drawn special effect map to obtain a special effect sub-image.

[0041] The above-mentioned pre-drawn special effect map may include one or more special effect particles. When there are multiple special effect particles, the types of the special effect particles may be different. For example, the special effect particles in the special effect map may include special effect particles such as water, fire, fog, gas, meteors, etc. If a virtual object can present multiple effects, in order to facilitate the subsequent generation of special effect maps, the pre-drawn special effect map may include a variety of different special effect particles, so that the special effect particle area can be selected according to actual needs to improve processing efficiency.

[0042] The above-mentioned special effect particle area may be an area containing one special effect particle, and correspondingly, the generated special effect sub-image contains only one special effect particle. The number of special effect sub-images is the same as the number of acquisitions. In order to achieve a random staggered special effect, the number of acquisitions can be multiple, and the number of corresponding special effect sub-images is also multiple. By including only one special effect particle in the special effect sub-image, the subsequent generation of the target special effect image can be more realistic.

[0043] Step S106 : for each special effect sub-image, a target special effect image corresponding to the special effect sub-image is generated according to the UV flow parameters corresponding to the special effect sub-image.

[0044] The above-mentioned UV flow parameters are used to characterize the special effect movement state corresponding to the special effect particles, and the special effect movement state may include the special effect movement speed, the special effect movement angle, the state of the special effect presentation (such as the offset degree of the special effect particles, the size of the special effect particles), etc.

[0045] The UV flow parameters corresponding to each of the above special effect sub-images can be set to different parameters. By setting different UV flow parameters, when multiple target special effect images are superimposed together, the special effects will appear randomly, making the effect presented on the virtual object more realistic and not rigid.

[0046] Step S108, superimposing each target special effect image with the object map to obtain a virtual object with special effects corresponding to the special effect particles.

[0047] When performing overlay processing, you can first determine the area to which special effects are to be added. Since the object map is an image that has been rendered, the selected area is the area on the virtual object with character materials, such as the virtual pendant of the virtual object, the wings of the virtual object, the clothes of the virtual character, etc.

[0048] When superimposing, the target special effect image can be directly superimposed, or the size of the target special effect image can be adjusted according to the area to which the special effect is to be added. In this way, the special effects corresponding to the special effect particles presented on the virtual object obtained after superposition will not have the problem of inappropriate position of the special effects, thereby improving the effect of the special effect display.

[0049] The special effects processing method provided by the embodiment of the present invention can obtain multiple special effects sub-images by collecting the special effects particle area in the special effects map a preset number of times, and generate a target special effects image with a relatively realistic special effects effect according to the UV flow parameters of the special effects sub-images. By superimposing the target special effects image and the object map, a virtual object displaying the real special effects can be obtained, thereby avoiding the separation of the special effects and the virtual objects and improving the display effect of the special effects on the virtual objects.

[0050] In one embodiment, the method can be implemented in a shader. When implemented in a shader, when obtaining an object map of a virtual object to which special effects are to be added, the reflective index map (i.e., albedo map) corresponding to the virtual object to which special effects are to be added can be first obtained, and the reflective index map is texture rendered and color rendered to obtain the object map of the virtual object. The object map of the virtual object obtained is a map with a character material. The use of the special effect particle trailing effect will cause the virtual character and the special effect to be separated. Therefore, the following processing method is used to add special effects to the special effect map of the virtual object.

[0051] In this embodiment, it is necessary to first determine a special effect map. In one implementation, the special effect map includes a background map and at least one special effect particle located in the background map, wherein the background map can be a black map, see Figure 2 The schematic diagram of special effect particles shown in Figure 2 In the example, the special effect particles are special effect particles that realize the meteor effect on the virtual object. By setting the background image to a black background image, the subsequent overlay operation will not affect the overlay effect.

[0052] In addition, the background image can also be set to other colors. When it is set to other colors except black, in order to ensure the overlay effect, the other colors need to be processed into black before overlaying.

[0053] After the step of obtaining the special effect sub-image, the terminal can also respond to the parameter adjustment operation for the special effect sub-image, and determine the UV flow parameters of the special effect sub-image according to the parameter adjustment operation; wherein the UV flow parameters include flow speed, flow direction and offset angle; wherein the offset angle is the offset angle of the starting point and end point of the special effect particle in the screen space coordinate system. For example, for meteor special effect particles, the starting point and end point of the star have a certain offset angle relative to the coordinate axis of the screen space, so that there will be a more realistic meteor falling effect when the special effect is realized; for smoke special effects, the angle of smoke diffusion is also different, so for different smoke special effect particles, the offset angles of different special effect sub-images are set differently, which can make the smoke special effect more realistic. For other special effect particles, the special effects can be improved by setting different UV flow parameters, which will not be repeated here.

[0054] In one embodiment, in order to achieve more realistic special effects on virtual objects, different UV flow parameters can be set for different special effects sub-images collected, so that the flow speed, flow direction, and offset angle of special effects particles in different special effects sub-images are different. By superimposing multiple special effects sub-images, a more random special effects effect can be produced, thereby improving the presentation effect of the special effects and the user's viewing experience of the special effects.

[0055] When collecting the special effect particle area in the pre-drawn special effect map to obtain the special effect sub-image, the special effect particle area can be first determined in the pre-drawn special effect map, and then the special effect map can be sampled according to the preset number of times for the special effect particle area to obtain multiple special effect sub-images corresponding to the preset number of times. The special effect particle area can include an area of ​​a special effect particle, so that multiple special effect sub-images containing a special effect particle can be obtained through multiple collections, so that it is convenient to assign different UV flow parameters to each special effect sub-image in the subsequent process, so as to obtain special effect images with different special effect flows. This method determines the special effect particle area and generates multiple special effect sub-images for the particle area, which is conducive to the subsequent generation of special effect images with more realistic special effect effects and improves the authenticity of the special effects.

[0056] For easier understanding, see Figure 3 As shown, Figure 3 (a) and Figure 3 The dotted box in (b) is the special effect particle area. Different dotted lines represent different flow speeds, and the arrow directions represent different flow directions. In addition, the offset direction of the meteor special effect particles can also be adjusted.

[0057] In order to control the range of special effects on the superimposed virtual character, in one embodiment, when each target special effects image and the object map are superimposed, a special effects mask image corresponding to the object map can be obtained, and the special effects mask image is superimposed with the target special effects image and the object map, thereby determining the range of special effects displayed on the virtual object based on the special effects mask image. Figure 4 A schematic diagram of a special effect mask image is shown in . This method can further improve the randomness of the special effects appearing on the virtual character, and further improve the effect of the special effect display.

[0058] In order to facilitate the operation of artists and improve their flexibility in processing, when each target special effect image is superimposed with the object map to obtain a virtual object with special effects corresponding to the special effect particles, the following two methods can be used:

[0059] Method 1, in response to a first superposition operation on multiple target special effect images, a target special effect map with special effects corresponding to special effect particles is generated; in response to a second superposition operation on the target special effect map and the object map, a virtual object with special effects corresponding to special effect particles is obtained.

[0060] Mode 2, in response to the third superposition operation on each target special effect image and the object map, each target special effect image and the object map are superimposed to obtain a virtual object with special effects corresponding to the special effect particles.

[0061] In order to ensure that the target special effect image and the object map are more realistic after superposition and avoid separation, when superimposing each target special effect image and the object map, each channel of the color space of the target special effect image can be superimposed with the corresponding channel of the color space of the virtual object to obtain a virtual object displaying the special effect.

[0062] This embodiment provides a schematic diagram of a virtual object displaying special effects. Figure 5 As shown, (a), (b), (c), and (d) are schematic diagrams of presenting special effects on virtual objects at different moments. The special effect is a meteor effect, and the location where it appears is on the wings of the virtual object. In actual applications, the location where the special effect appears can be selected from other locations. This is just an example. Figure 5 In a, the meteor is displayed on the right wing of the virtual object (corresponding to the left wing shown in the figure). Figure 5 In b, the meteor is displayed on the left wing of the virtual object (corresponding to the right wing shown in the figure). Figure 5 In c, no meteors are displayed. Figure 5 In d, the meteor is displayed on the left wing of the virtual object and is Figure 5The positions of the meteors in b are different. Since the positions of the special effects on the virtual objects are different at different times, it is more in line with the random characteristics of the meteor special effects, making the effect of the meteor special effects on the virtual objects more realistic.

[0063] In one example, an RGB color space may be selected, and the RGB channel of the target special effect image and the RGB channel of the object map may be added to obtain a virtual object displaying the special effect.

[0064] In one implementation, when the object map is an albedo map and the target special effect image is a meteor map, the meteor map rgb and albedo.rgb can be directly added to obtain a virtual object displaying the special effect.

[0065] In summary, the special effects processing method provided in the embodiment of the present invention can generate a target special effects image with relatively realistic special effects, and can obtain a virtual object that displays real special effects, thereby avoiding the separation of special effects and virtual objects and improving the display effect of special effects on virtual objects.
