Material Class
This class is used to create materials, which are assigned to each node (or each surface of the object) and define how they look like. They implement the shaders and control what options, states, parameters of different types and textures are used to render the node during the rendering passes.
The concepts of a path and a name of the material should be distinguished:
- The path specifies where the material is stored on the disk. The path includes a material file name.
- The name specifies how the material will be displayed in Materials Editor (the materials hierarchy, the nodes surface editor). The name can also be used to reference material from the code.
Usage Examples
Changing Textures
The first example describes how to set texture flags to the material's texture. We set the ANISOTROPY_8 flag to the albedo texture of the mesh_base_0 material.
In the console, you can see the following result:
Output
Image texture flags are: 81920
Image texture flags are: 524288Flags are bits of the integer variable: 81920 value means the FILTER_BILINEAR flag, 524288 value means the ANISOTROPY_8 flag.
Changing States and Parameters
The second example illustrates how to inherit a material from the mesh_base, enable the planar reflection state and change two parameters affecting the look of dynamic reflections.
