In a cross-platform transplantation game, the problems of picture effects and performance differences of different platforms are often considered. Under the condition of ensuring the performance, the picture effects of different platforms are relatively consistent as much as possible. At present, in order to enable old model resources to match the game effect of a new platform, the game scene is required to be modified usually. In this case, after the new game model is created in the three-dimensional creation software, the map drawn by the map creation tool is created (the map is intended to allow the model to have a model effect, and a model without a map is a gray model without colors), and after the map of the game model is created, the game model and the map are input to the game engine and rendered, and then the rendering effect of the game model and the map by the map creation tool is greatly different due to scene changes (mainly, the difference in screen effect between the model in the map creation tool and the model in the game scene of the game engine).
Among the reasons for this difference are: different software, the software bottom layer structure is different (such as the calculation mode of illumination); the models are in different environments, the game scenes generated in a general game engine are illuminated by spotlights, and HDRI maps are used in a mapping tool for providing illumination; the material calculation of the model in different software is different.
In the related art, usually, a method of repeatedly modifying a map drawn by a map making tool is used, so that after a finally drawn map and a game model are input to a game engine for rendering, a rendering effect in a game scene of the game engine is consistent with a rendering effect in the map making tool.
In addition, the rendering effect of the model in the mapping tool can be set through previewing the scene by the model in the game engine, but the method can only be similar to the effect of previewing the scene by the model, the effect of the model in the game scene of the game engine and the effect drawn by the mapping tool cannot be synchronized, the mapping drawn by the mapping tool needs to be repeatedly modified, and the efficiency is low.
Based on this, the method and the device for drawing the model map and the electronic device provided by the embodiment of the invention can be applied to electronic devices such as computers and notebooks.
To facilitate understanding of the embodiment, a detailed description is first given of a method for drawing a model map according to the embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, scene resources of a target game scene generated by a game engine tool and material resources of an initial game model are obtained;
the game Engine tool may also be referred to as a game development Engine tool, for example, a fantasy 4 Engine (ue 4), and the target game scene generally refers to an environment in which a virtual character is located in a target game, and generally includes various virtual plants, buildings, sky, illumination, and the like. The scene resources generally include lighting resources, execution code for rendering a scene, and the like. The initial game model is usually modeled by a three-dimensional modeling tool, and the initial game model is usually a gray model without a model effect, and naturally, resources such as material are not provided. The texture resources are those generated in advance by the game engine tool for the initial game model, and are usually obtained from a texture system of the game engine tool, where the texture system of the game engine tool corresponds to a shader (shader) and can perform various calculations in the shader to generate different screen effects.
In actual implementation, in the game engine tool, information such as lighting information in a target game scene, rendering information for rendering the target game scene, mapping information, and correction may be obtained, so as to enable the initial game model to be in an environment similar to an actual game scene, and draw a model map. Meanwhile, the material resources of the initial game model are also required to be acquired, and the material resources usually comprise model material calculation, such as color information, light and shadow information, metal degree, roughness map, highlight and other information of the model map.
The specific resource obtaining mode may be direct obtaining or obtaining through a preset obtaining mode.
Step S104, determining shader resources in the map drawing tool according to the scene resources and the material resources; wherein, the shader resources are used for simulating the model rendering effect of the game engine tool;
the mapping tool is mainly used for making model mapping for the initial game model. For example, the Substance pointer software, SP for short, is a powerful 3d texture mapping software, provides a large number of brushes and materials, and can design a model mapping meeting requirements. The shader (shader) resources generally include information such as graphics card execution codes and instructions, and are mainly used for describing a process of rendering a model, and various calculations can be performed to generate different model effects. The method is mainly used for simulating the rendering effect of the model in the game engine tool in the mapping tool, such as the material of the model, the roughness of the surface of the model, the color of the surface of the model, the highlight of the surface of the model and the like. So that the model rendering effect of the initial game model in the charting tool is similar to or even consistent with the model rendering effect in the game engine tool.
Specifically, the scene resources may be directly set in the game scene in the mapping tool, so that the scene environment of the initial game model in the mapping tool, such as information such as lighting, is similar to or even consistent with the scene environment in the actual game scene (i.e., the target game scene generated by the game engine tool). Information such as scene calculation in the scene resource can also be set in a shader in the map drawing tool to obtain the shader resource, so that the scene environment, such as color and other information, of the initial game model in the map drawing tool is similar to or even consistent with the scene environment in the actual game scene (i.e., the target game scene generated by the game engine tool).
Meanwhile, the material resources can be set in a shader in the mapping drawing tool, and the shader resources are obtained. Specifically, various information in the resource may be directly written into a shader in the map drawing tool, or the target information in the material resource may be selected and written into the shader in the map drawing tool. Because the material resources are resources such as material calculation aiming at the initial game model in the game engine tool, the model rendering effect of the game engine tool can be simulated through the shader resources.
Step S106, in the map drawing tool, drawing the model map of the initial game model based on the scene resources and the shader resources.
Specifically, the lighting information and the like in the scene resource may be set in the game scene in the mapping tool, for example, a map is set for the scene model. Shader resources are assigned to the initial game model such that the initial game model has a model effect. And then drawing a model map for the initial game model in the game scene and on the basis of the model effect, wherein based on the model map, after the model map is rendered in a game engine tool by the initial game model, the displayed model effect is similar to or even consistent with the rendering effect in the map drawing tool. Meanwhile, the rendering effect in the actual game scene is consistent with the preset rendering effect.
The embodiment of the invention provides a method for drawing a model chartlet, which comprises the steps of obtaining scene resources of a target game scene generated by a game engine tool and material resources of an initial game model; determining shader resources in the map drawing tool according to the scene resources and the material resources; in the map rendering tool, a model map of the initial game model is rendered based on the scene resources and shader resources. In the mode, shader resources in the mapping drawing tool are set through scene resources and material resources in the game engine tool, so that when the model mapping of the initial game model is drawn, the mapping drawing tool can simulate the model rendering effect in the game engine tool, the problem that the model mapping is repeatedly modified due to inaccurate drawn model mapping and different model effects in different tools of the initial game model is solved, the efficiency of drawing the model mapping is improved, and meanwhile the development efficiency of the game model is improved
In the related technology for obtaining the HDR map of the game scene, only the model of the game scene can be obtained, information such as lamplight and post-processing cannot be captured, and the lamplight information needs to be forged by using the model in the later period. Based on the above, another method for drawing a model map is described below, where the scene resources include HDR (High-Dynamic Range) maps of target game scenes; among them, the HDR map may also be called an HDRI map, and in image software such as 3D, there is an environment map with a high dynamic range. It plays an important role in: as an environmental background (e.g., rendering a building model, blue sky cloudlet trees in the background, etc. can be used to make this map). The method is mainly used for rendering illumination in the game scene in the mapping tool as the environment background. In this embodiment, a step of acquiring scene resources of a target game scene generated by a game engine tool is mainly described, and as shown in fig. 2, the method specifically includes the following steps:
step S202, setting a three-dimensional model at the illumination position of a target game scene, and endowing a preset target material to the three-dimensional model;
the three-dimensional model can be a sphere model, the illumination position refers to the position of light in a target game scene, and the preset target material can be a parameter with a self-illumination function and is mainly used for enabling the three-dimensional model to have the illumination function. Specifically, a body model, such as a sphere model, is newly established in a target game scene in the game engine tool, the newly established model is copied to a lighting position of the target game scene, specifically, lighting can be clicked on a display interface of the target game scene, that is, a position parameter of the lighting can be displayed on the attribute bar, and then the position parameter can be clicked by right clicking, so that the three-dimensional model can be copied to the lighting position. Then, a target material, such as a material ball, is newly built, and the target material is endowed to the three-dimensional model.
Step S204, adjusting self-luminous parameters of the target material; the target material simulates illumination information of a target game scene through self-luminescence parameters;
the self-luminescence parameters generally include a color parameter and an intensity parameter of the lamp light. Specifically, the self-luminous parameters of the target material can be adjusted according to experience, and the self-luminous parameters of the target material can be adjusted according to the attribute information of light in the target game scene, such as color attribute, intensity attribute and the like, so that the illumination information of the target game scene can be simulated by the adjusted target material.
Step S206, acquiring an HDR map of a target game scene in a preset cube capturing mode; the HDR map comprises illumination information of target material simulation, and is used for providing illumination for a game scene in the map drawing tool.
The cube capturing manner specifically includes: adding a Scene capturing Cube of Scene Capture into a Scene of a Target game, creating a Cube Render Target in a Scene Capture Cube detail panel, adding the Cube Render Target to a texture Target in the Scene Capture Cube, capturing 360 images of the position of the Scene Capture Cube in the Scene of the Target game by the Cube Render Target at the moment, creating static texture in the Cube Render Target, and obtaining the HDR map of the Scene of the Target game. In the mode, the self-luminous model is established at the light position of the target game scene, and the self-luminous parameters are adjusted at the same time, so that the illumination of the target game scene can be simulated, and further the illumination information of the target game scene, namely HDR (high-resolution graphics) chartlet can be obtained, the effect synchronization of the game scene in different tools is improved, and the accuracy of model chartlet is further improved.
The illumination information comprises illumination intensity and/or illumination color; in the step S204, the step of adjusting the self-luminescence parameter of the target material is, in one possible implementation manner:
adjusting an intensity parameter in the self-luminous parameter of the target material according to the intensity attribute of illumination in the target game scene; and/or adjusting color parameters in the self-luminous parameters of the target material according to the color attributes of illumination in the target game scene.
Specifically, the interface of the target game scene displayed by the game engine tool includes a light attribute panel, and the color, such as Lightcolor, can be directly copied from the light attribute panel, and the color value is copied and then pasted to the color parameter of the self-luminous parameter of the target material. Similarly, the intensity value may be copied directly from the light attribute panel and then pasted into the intensity parameter of the self-illumination parameter of the target material. In addition, in the self-luminous parameters of the target material, the color parameters and the intensity parameters are provided with adjusting nodes, and the color parameters and the intensity parameters can be adjusted according to the exposed parameters of the nodes and the actual conditions. In the mode, the self-luminous parameters of the target materials can be adjusted according to the light attributes in the target game scene, so that the synchronization of the illumination effects of the game scene in different tools is further improved, and the accuracy of model mapping is further improved.
It is understood that the step of adjusting the self-luminescence parameters of the target material, one possible implementation: the intensity parameter in the self-luminescence parameter of the target material can be adjusted according to the intensity attribute of the illumination in the target game scene. Or adjusting the color parameter in the self-luminescence parameter of the target material according to the color attribute of illumination in the target game scene. The intensity parameter in the self-luminous parameter of the target material can be adjusted according to the intensity attribute of illumination in the target game scene; and adjusting color parameters in the self-luminescence parameters of the target material according to the color attributes of the illumination in the target game scene.
In addition, it should be noted that the light information cannot be perfectly synchronized, and only approximate simulation is possible, which depends more on the experience of art workers, but some auxiliary methods are available. Based on this, after the self-illumination parameters are adjusted, in order to further improve the synchronization of the illumination effect of the game scenes in different tools, a color calibration model (also called color calibrator model, which is a model commonly used in film and television, and is generally used for observing the color change in different lighting environments) is preset, and the material resources are synchronized.
In the color block part of the color calibration model, a color block map is sampled from the material of the game engine tool to be used as a basecolor, the metal degree input value is 0, and the roughness input value is 0.95. In the mapping tool, the color calibration model is given a default standard shader, sample color squares, a metal degree input of 0, and a roughness input of 0.95.
In the bead part of the color calibration model, in the material of the game engine tool, basecolor is given a color of float3 (0.8 ) in gray, the degree of metallization is given 1, and the roughness is given 0.1. In the mapping tool, the color calibration model is given a default standard shader, basecolor, a float3 (0.8 ) gray color, a 1 for the degree of metallization, and a 0.1 for the degree of coarseness.
The non-metallic ball part of the color calibration model, in the material of the game engine tool, basecolor is given a float3 (0.18 ) gray, the degree of metallization is given 0, and the roughness is given 0.85. In the mapping tool, the color calibration model is given a default standard shader, basecolor, a float3 (0.18 ) gray, a degree of metallization 0, and a roughness 0.85.
The steps can complete material synchronization of the color calibration model, then the model rendering effect of the obtained HDR chartlet in the game scene in the chartlet drawing tool is compared with the model rendering effect in the game engine tool, and the self-luminous parameters are adjusted according to the practicability of the comparison result. For example, if the rendered model effect difference is observed to be large, the self-luminescence parameters in the body model material in the game engine tool need to be readjusted, and the HDR map of the adjusted target game scene needs to be obtained again. This may be repeated until the color calibration model is close in effect in the game engine tool and in the charting tool.
In the above step of determining shader resources in the map drawing tool according to the scene resources and the material resources, a possible implementation manner is:
(1) In the charting tool, creating initial shader resources for an initial game model;
(2) And synchronizing the scene resources and the material resources to the initial shader resources to obtain the shader resources in the mapping drawing tool.
Specifically, first, an initial shader resource, which is a base of the initial game model, is created in the mapping tool, and the initial shader resource is a custom resource. The material calculation usually includes: samples of basecolor maps (providing color information), samples of Normal maps (providing shadow details), samples of metallization levels, roughness maps, and specula (highlight) values.
Specifically, the computing resources and the material resources in the scene resources other than the HDR map may be synchronized to the initial shader resources, or the computing resources and the material resources in the scene resources other than the HDR map may be synchronized to the initial shader resources, which are different from the initial shader resources. In the method, in the map drawing tool, a self-defined shader resource is firstly created, and then the scene resource and the material resource are synchronized, so that the operation flow is simplified, and the drawing and development efficiency is improved.
The scene resource further includes: a first execution code for tone mapping and a second execution code for color correction; the first execution code of tone mapping may be denoted tonemapping and the second execution code of color correction may be denoted colordirect.
In the foregoing step of synchronizing the scene resources and the material resources to the initial shader resources to obtain shader resources in the map drawing tool, a possible implementation manner is as follows:
(1) Writing the material resource into the initial shader resource to obtain a first shader resource in the mapping drawing tool;
the texture resource may be a different resource from the initial shader resource, or may be a target resource in the texture resource. Specifically, the material resources may be written into the initial shader resources entirely, or part of the material resources may be selectively written into the initial shader resources, or the specific information in the material resources may be written into the initial shader resources.
(2) And writing the first execution code of the tone mapping and the second execution code of the color correction into the first shader resource to obtain the shader resource in the mapping drawing tool.
The first execution code of tone mapping and the second execution code of color correction can be generally called as the post-processing of the game scene, and are mainly used for mapping the tone of the target game scene and correcting the mapped tone, so that the game scene in the mapping tool is more synchronous with the color environment of the actual game scene. In the above manner, the synchronization between the game scene and the actual game scene in the mapping tool is further improved and the rendering effect of the model in the mapping tool is improved by writing the initial shader resource material resource, the first execution code of tone mapping and the second execution code of color correction.
The step of writing the material resource into the initial shader resource to obtain the first shader resource in the tile drawing tool comprises: and writing the third execution code of the highlight calculation into the initial shader resource to obtain the first shader resource.
It should be noted that, in general, the texture resources are the same as the samples of the basecolor map (providing color information), the samples of the Normal map (providing shadow details), and the samples of the metallization and roughness maps in the initial shader resources. Wherein the reflection information is provided by means of a metallization and roughness map, the two maps being grey scale maps, only black, white and grey for recording values, black being 0, white being 1, grey being values between 0 and 1. They determine whether the texture of the model is smooth or rough, metallic or non-metallic. However, the third code for highlight calculation in the material resource, i.e. the Specular value, is different from that in the initial shader resource, so that the third code for highlight calculation in the material resource needs to be written into the initial shader resource.
Wherein the Specular value in the material resource is obtained by (1-roughness map) Specular value (the Specular value is regarded as 0.2 by default). But default in the initial shader resources is to sample a specularie _ tex (the highlight map is called specularie in the mapping tool) map to obtain specularie value. Therefore, it is necessary to write the SpecularLevel = (1-roughness) × 0.2, roughness is roughness map, and the inner 0.2 is SpecularValue in the material resource, into the initial shader resource.
In the above manner, the third execution code of highlight calculation in the material resource, i.e. the special value, is written into the initial shader resource, so that the material calculation difference between the game engine tool and the mapping tool is eliminated, the rendering effect of the initial game model in the mapping tool is improved, and the synchronization between the rendering effect and the rendering effect of the initial game model in the game scene of the game engine is improved.
In the above step of drawing a model map of an initial game model based on scene resources and shader resources, a possible implementation manner is as follows: setting the HDR map in the scene resources as a model map of a target game scene model in a map drawing tool, endowing shader resources to an initial game model, and simulating the model effect of the initial game model; and drawing a model map of the initial game model based on the model effect of the initial game model.
In actual implementation, the shader resources are assigned to the initial game model, and the rendering effect of the initial game model is changed. Meanwhile, a scene model (for example, a sphere model, which can be understood as a sky sphere) is created in the chartlet drawing tool, corresponding to the target game scene, and then the HDR chartlet is placed in the chartlet drawing tool and set as the HDR chartlet of the scene model, so that the scene model has illumination similar to that of the target game model, and thus the target game scene can be simulated in the chartlet drawing tool, and meanwhile, the model effect (such as highlight, roughness and the like of the model) of the initial game model in the game engine tool is simulated. In the model effect and the game scene, the model map of the initial game model is drawn, so that the drawn model map has higher accuracy.
