All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
Additionally, the flowcharts used in this application illustrate operations implemented according to some embodiments of the present application.

One skilled in the art, under the guidance of this application, may add one or more other operations to, or remove one or more operations from, the flowchart.
To enable one skilled in the art to use the present disclosure, in connection with specific application scenarios: the rendering of a game scene is an example, and the following embodiments are given. It will be apparent to those skilled in the art that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application. Although the present application is primarily described in the context of rendering of a game scene, it should be understood that this is merely one exemplary embodiment.

shader (Shader): the Shader stores execution codes of the GPU, is used for informing the GPU of how to draw the color of the target pixel, and is widely applied to the field of three-dimensional graphics. Various three-dimensional graphic effects can be obtained through the shader code.
Direct light (Direct light): light that is emitted from a light source directly onto an object is called direct light.
Indirect light (Indirect light): in the real world, objects can be illuminated by indirect lighting. Indirect lighting means that light is generally reflected between objects and finally enters the camera, i.e. the light is reflected by more than one object before entering the camera.
A Physical Based Rendering (PBR) is a real-time Rendering method widely used in recent years, and a material system corresponding to the PBR is called a PBR material system, and the PBR material system includes a plurality of parameters such as a Base Color (basic Color), a metal degree (Metallic), and a Roughness (Roughness).
Ambient reflection (IBL): in the PBR system, high light reflection is achieved by IBL technology. The effect of ambient light in a real-time rendering is achieved by using an environment map (which may be a real-world camera shot or a real-time rendering of an in-game camera).
Rendering the pipeline: the rendering pipeline is a core component of real-time rendering. The rendering pipeline functions to render a two-dimensional image by giving scene elements such as a virtual camera, a three-dimensional scene object, and a light source.

The following is illustrated in connection with rendering of a virtual snow layer in a game scene. Fig. 6 is a schematic configuration interface diagram provided in an embodiment of the present application, and as shown in fig. 6, a current game scene rendering method is exemplarily explained as an example of rendering of a snow layer in a game scene: the object texture shader configuration interface may be, for example, a terrain mosaic texture shader configuration interface, and the configuration interface may include, for example, parameter configuration areas such as terrain standard parameters and snow base color parameters, and in addition, a second configuration area 130 may be additionally provided on the object texture shader configuration interface for receiving second texture rendering parameters; at this time, in the Snow Layer, besides the configuration areas of the standard parameters and the basic parameters, two configuration areas are also layered: the first configuration area 120 and the second configuration area 130 are respectively used for reading different degrees of metallization and roughness corresponding to the bright part area and the dark part area, and performing subsequent material rendering on an object to be rendered in the current game scene according to the read parameters.
Wherein: the first layer is to read a first material rendering parameter through a first configuration area 120, namely, a snow layer mixed parameter SnowLayer Mix interface, the interface reads a material map, wherein a R channel in the material map stores a metal value, and a G channel in the material map is a roughness value, the first material rendering parameter is determined according to the two read parameters, and then the material rendering is performed on a bright part area directly irradiated by light according to the first material rendering parameter, if an artist needs to modify the material effects of the two areas in the current game scene, the first material rendering parameter corresponding to the interface can be modified directly by modifying the material map, so that the material effect corresponding to the bright part area in the current game scene is adjusted.
The second layering is to read a second material rendering parameter through a second configuration area 130, namely a snow layer metal degree specification parameter SnowLayerSpecCube Metallic interface and a snow layer Roughness specification parameter SnowLayerSpecCube roughnessinterface, and then perform material rendering on a dark part area which is not directly irradiated by light according to the second material rendering parameter; the two interfaces in the second configuration area 130 are used for reading corresponding material rendering parameters, which respectively allow to receive a value ranging from 0 to 1, and different values correspond to different roughness or metallization, and are used for subsequently processing the metallization and the roughness of the dark portion area according to the read values of the two interfaces; in the process of configuring the game scene, if an artist needs to modify the material effect of the dark area in the current game scene, the material effect corresponding to the dark area in the current game scene can be adjusted directly on the first configuration area 120 and the second configuration area 130 corresponding to the parameter configuration interface by modifying the material rendering parameters respectively corresponding to the two interfaces.
In the method provided by the application, the PBR calculates two different metal degrees and Roughness values which are used for processing the bright part material effect and the dark part material effect in the current game scene, wherein in the IBL part, the metal degrees and the Roughness values required by the IBR are increased by using the method provided by the application, and the second configuration area comprises two interfaces (SnowLayerSpecCube Metallic and SnowLayerSpecCube Roughness).
By adopting the game scene rendering method provided by the application, the target bright part area and the target dark part area are rendered respectively through the configuration results of the first material rendering parameter and the second material rendering parameter in the first configuration area and the second configuration area, and compared with the mode of rendering the dark part area according to the interaction of direct light and indirect light in the traditional technology, the rendering method provided by the application is simple and easy to operate and modify, and is convenient for an art worker to control the effect of the bright part and the dark part of any material in the game scene by adjusting the first material rendering parameter and the second material rendering parameter.
