Surface#
A Surface object encapsulates all visual information used for rendering an entity or its sub-components (links, geoms, etc.)
The surface contains different types textures: diffuse_texture, specular_texture, roughness_texture, metallic_texture, transmission_texture, normal_texture, and emissive_texture. Each one of them is a gs.textures.Texture object.
Note
Most advanced surface types are only supported by cameras using the RayTracer rendering backend. If Rasterizer is used, only color will be rendered.
