Description

Technical Field

[0001] The present application relates to the field of three-dimensional computer graphics technology, and in particular to a texture production method, device, equipment and computer-readable medium. Background Art

[0002] Stylized textures are frequently used in games, advertisements, film and television productions, and short videos, such as hand-drawn and anime-style photos. A consistent style is crucial in game development. For example, a cyberpunk-themed game should feature cyberpunk-style textures for its models, scenes, and lighting effects. An 2D-themed game should also feature 2D-themed textures for each in-game texture.

[0003] Currently, in related technologies, the unified production of texture styles can be achieved through the generator that comes with the game engine. However, the generator cannot make all objects in the entire texture have exactly the same effect. For the differences in effects between objects, additional differences need to be eliminated, resulting in low efficiency in the production of stylized textures, which may even seriously affect the progress of game development.

[0055] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0057] In related technologies, unified texture style production can be achieved through the generator that comes with the game engine. However, the generator cannot make all objects in the entire texture have exactly the same effect. For the differences in effects between objects, additional differences need to be eliminated, resulting in low efficiency in the production of stylized textures, which may even seriously affect the progress of game development.

[0058] In order to solve the problems mentioned in the background technology, according to one aspect of the embodiments of the present application, an embodiment of a texture production method is provided.

[0059] Optionally, in the embodiment of the present application, the above-mentioned mapping method can be applied to Figure 1 In the hardware environment composed of the terminal 101 and the server 103 shown in FIG. Figure 1 As shown, the server 103 is connected to the terminal 101 via a network, and can be used to provide services (such as texture baking, texture production, etc.) for the terminal or the client installed on the terminal. A database 105 can be set on the server or independently of the server to provide data storage services for the server 103. The above-mentioned network includes but is not limited to: wide area network, metropolitan area network or local area network, and the terminal 101 includes but is not limited to PC, mobile phone, tablet computer, etc.

[0060] A sticker making method in the embodiment of the present application can be executed by the server 103, or can be executed by the server 103 and the terminal 101 together, such as Figure 2 As shown, the method may include the following steps:

[0061] Step S202: determining a target object for which a texture is to be created, and baking a first texture of the target object, wherein the first texture is used to record inherent color information of the target object;

[0062] Step S204, adding ambient occlusion light and concave-convex information to the first map to obtain a second map;

[0063] Step S206, adding a texture effect and a color block effect to the second map, so as to add texture details and color details to the second map, thereby obtaining a third map;

[0064] Step S208, when the detail feature of the third map reaches the first target threshold, adding light and shadow effects to the third map to obtain a fourth map;

[0065] Step S210, synthesizing the first map, the second map, the third map, and the fourth map to obtain a base color map and a roughness map of the target object, exporting the base color map and the roughness map and inputting the base color map and the roughness map into a preset block model, and obtaining a hand-painted style map of the target object output by the preset block model.

[0066] This application optimizes the texture production process, especially the hand-painted texture production process, through steps S202 to S210, thereby improving the production efficiency of hand-painted textures, and further enhances the color block effect by using a preset color block model, thereby reducing the effect differences of objects in the same environment.

[0067] In step S202, the target object is an object displayed in the game, such as a person, a building, flowers, a mountain, a stream, etc. Baking refers to saving the light and dark information of the object's lighting to the texture. During real-time rendering, lighting calculations are no longer performed, but pre-generated lighting textures are used to represent various effects. Baking technology eliminates the need for lighting calculations and can increase rendering speed. The above-mentioned first map is used to record the inherent color information of the target object, that is, the first map can be the inherent color map of the target object. The inherent color map records the sum of the color effects presented by the object under white sunlight. To bake the inherent color map, the following steps can be followed:

[0068] Step 1: illuminate the target object with a uniform white light source and capture an image of the target object with a virtual camera;

[0069] Step 2: remove the shadows in the image to obtain the intrinsic color map.

[0070] In step S204, adding ambient occlusion light and bump information to the first map to obtain a second map specifically includes the following steps:

[0071] Step 1: Add ambient occlusion light to the first map to obtain a first intermediate map. Specifically: bake out the ambient occlusion map of the target object; put the ambient occlusion map in the base color channel of the first newly created layer, and mix the colors of the corresponding pixels of the ambient occlusion map and the first map in the base color channel of the first newly created layer, wherein the color of the pixel on the first map is used as the base color, and the color of the pixel on the ambient occlusion map is used as the mixed color. The base color and the mixed color are mixed to obtain the result color, and the base color channel is the rendering channel in the map making tool; save the result color obtained by mixing each pixel in the first newly created layer to obtain the first intermediate map.

[0072] In an embodiment of the present application, a texture can be made based on a texture creation tool such as Substance Painter. The base color channel is a rendering channel in the texture creation tool. Ambient occlusion light is added to the first texture to obtain a first intermediate texture. A first new layer is created, and the occlusion map and ambient occlusion map baked using the target object are placed in the base color channel of the first new layer. The ambient occlusion map and the first texture (intrinsic color map) are mixed in the base color channel of the first new layer, such as by multiplying, to obtain a first intermediate texture. The ambient occlusion map is used to draw the effect of blocking the surrounding diffuse light when objects intersect or are close to each other. It mainly achieves better image details by improving shadows. After the model is made, the ambient occlusion map is not directly attached to the material ball, but the intrinsic color is drawn. For example, if it is placed on the intrinsic color material in the form of multiplying on the ambient occlusion map, the light and dark of the object will be more realistic. Multiply is a blending mode in computer graphics software such as Adobe Photoshop. It exists in the darkening mode group that includes color blending modes, channel blending modes, and layer blending modes, and is a frequently used darkening mode. Multiply multiplies the base color with the blended color. The resulting color is always a darker color. Any color multiplied with black produces black, while any color multiplied with white remains unchanged. When painting with colors other than black or white, continuous strokes drawn with painting tools produce gradually darkening colors. In this step, placing the ambient occlusion map on the base color channel of the first newly created layer actually uses the ambient occlusion map as the intrinsic color of the first newly created layer. The intrinsic color of the first map is then multiplied with the intrinsic color of the first newly created layer to produce the first intermediate map.

[0073] Step 2: Add a bump texture to the first intermediate map to obtain a second intermediate map. Specifically: bake out the curvature map of the target object; place the curvature map on the base color channel of the second new layer and overlay it with the first intermediate map to obtain the second intermediate map.

[0074] In an embodiment of the present application, a curvature map is a texture that stores the convexity / concavity of a mesh, which can be used to cover areas where the surface will be more worn or where subsurface scattering may occur (convex surfaces), where more dirt may accumulate (concave surfaces), to check the continuity of the surface, etc. The curvature map allows the extraction and storage of convex and concave information. Black values ​​represent concave areas, white values ​​represent convex areas, and gray values ​​represent neutral / flat areas. The step of obtaining the second intermediate map is to create a second new layer, and place the curvature map of the target object on the base color channel of the second new layer. The rendering mode of the base color channel is selected as overlay, and the curvature map and the above-mentioned first intermediate map are superimposed on the base color channel of the second new layer to obtain the second intermediate map.

[0075] Step 3: Use the inverted information of the ambient occlusion light to perform roughness filtering on the second intermediate map to obtain the third intermediate map. Specifically: invert the ambient occlusion map to obtain the first inverted map; place the first inverted map on the roughness channel of the third newly created layer to perform roughness filtering on the second intermediate map to obtain the third intermediate map.

[0076] In this embodiment of the present application, the roughness channel is the rendering channel of a layer in the texture creation tool. The step of obtaining the third intermediate map is to create a third new layer, invert the original occlusion map and ambient occlusion map to obtain a first inverted map, then place the first inverted map on the roughness channel of the third new layer, select Filter as the rendering mode, and perform a roughness filter on the first inverted map and the second intermediate map in the roughness channel of the third new layer to obtain the third intermediate map.

[0077] Step 4, use the inverted information of the bump texture to perform roughness screening or superposition on the third intermediate map to obtain a second map. Specifically: when the roughness of the target object is within the first range, invert the curvature map to obtain a second inverted map, and place the second inverted map on the roughness channel of the fourth newly created layer to perform roughness screening on the third intermediate map to obtain the second map; or, when the roughness of the target object is within the second range, invert the curvature map to obtain a second inverted map, and place the second inverted map on the roughness channel of the fourth newly created layer to perform roughness superposition with the third intermediate map to obtain the second map.

[0078] In the embodiment of the present application, the step of obtaining the second map is to create a fourth new layer, and invert the original curvature map to obtain a second inverted map, and then place the second inverted map on the roughness channel of the fourth new layer, select filtering or overlay in the rendering mode, and filter or overlay the second inverted map and the third intermediate map in the roughness channel of the fourth new layer to obtain the second map. Whether to filter or overlay can be selected according to the effect, specifically: if the overall roughness of the object (target object) is grayish white, filtering can be used, such as stone and wood; if the overall roughness of the object is dark gray and black, overlay can be used, such as metal, mainly based on the roughness of the object in the actual scene. The specific division of the above-mentioned first range and second range can be set according to actual conditions.

[0079] In step S206, a texture effect and a color block effect are added to the second map to add texture details and color details on the basis of the second map, and the third map is obtained, including:

[0080] Step 1: Create a first fill layer for the second map and determine the base color and roughness of the first fill layer to add texture to the surface of the second map.

[0081] Step 2, adding a first mask to the first fill layer to add a color block effect to the texture through the first mask to obtain a third map;

[0082] Step 3, when the detail characteristic degree of the surface details added to the second map by the third map does not reach the first target threshold, continue to create a new first fill layer, add texture and color block effect to the new first fill layer, and use the new first fill layer as another third map to continue adding surface details to the second map, until the detail characteristic degree of the surface details added to the second map reaches the first target threshold, and then save all the third maps.

[0083] In this embodiment of the present application, a mask can be added to enhance the surface details of the second map to create a blocky, hand-painted effect. Adding a mask requires creating a new fill layer for the second map. After adding the mask, the parameters of the first mask can be adjusted using the Blur Slope filter. A directional blur filter can also be added to the first mask, adjusting the parameters of the first mask based on the blur effect. Finally, a Sharpen filter can be added to enhance contrast and sharpen the image. Finally, the first fill layer is saved as a third map. The third map obtained through the above steps can be used to add surface details to the second map. The detail characteristic of the surface details can be expressed using factors such as resolution and the number of display elements. If the detail characteristic of the surface details added to the second map by the third map does not reach a first target threshold, new fill layers can be repeatedly created and texture and blocky effects can be added to the new fill layers. This new fill layer can then be used as a new third map to further enrich the surface details of the second map. Ultimately, when the detail characteristic of the surface details added to the second map by all third maps reaches the first target threshold, all third maps are saved. The first target threshold can be set according to the actual situation. Figure 3 shown.

[0084] In step S208, when the detail feature of the third map reaches the first target threshold, light and shadow effects are added to the third map to obtain a fourth map including:

[0085] Step 1: Create a second fill layer for the third map and determine the base color and roughness of the second fill layer.

[0086] Step 2: Add a second mask and lighting to the second fill layer to add light and shadow effects to obtain the fourth map.

[0087] In this embodiment of the present application, light and shadow effects can be added to the surface of the third texture by adding a mask. Adding a mask requires creating a new fill layer for the third texture. After adding a mask to the second fill layer, the second fill layer is saved as a fourth texture, so that the fourth texture can be used to add light and shadow effects to the third texture.

[0088] In the embodiment of the present application, the transparency values ​​of all maps can be changed in percentage according to the effect.

[0089] In an embodiment of the present application, adding texture effects and color block effects and adding light and shadow effects can be performed simultaneously, such as copying the second map to obtain a copy of the second map, adding texture effects and color block effects on a second map, and adding light and shadow effects on the copy of the second map. It is also possible to first add light and shadow effects to the second map, and then add texture effects and color block effects.

[0090] In step S210, in order to improve the color block effect of the fourth map, optimize the production effect of the map production tool, and reduce the difference in the hand-painted style display effect, the first map, the second map, the third map and the fourth map can be synthesized based on the above-mentioned first map, the second map, the third map and the fourth map to obtain the base color map and the roughness map of the target object, and the base color map and the roughness map are input into the preset color block model to obtain the hand-painted style map of the target object output by the preset color block model. The preset color block model can be the color block module in the Photoshop software. The hand-painted style map output by the final preset color block model can be as follows Figure 4 As shown, Figure 4 The two pictures on the left show the hand-drawn wind texture effects of the model alone, and the one on the right shows the hand-drawn wind texture display effect of the model in the actual game scene.

[0091] Specifically, the base color map and roughness map of the target object are obtained by synthesizing the first map, the second map, the third map and the fourth map. Figure 1 Combine them to get the base color map and roughness map of the target object. In addition, if there are multiple third maps, all third maps need to be combined. Figure 1 Synthesis.

[0092] The above-mentioned texture production method provided in this application can exist as a plug-in. After adding and running the plug-in in the texture production software, hand-painted style textures can be automatically generated according to user needs.

[0093] This application improves the efficiency of hand-painted style texture production and reduces the effect differences of objects in the same environment by optimizing the texture production process, especially optimizing the texture production process of hand-painted style textures.
