This page introduces the principles and theories related to materials exported through the Material Export function. Take MI_Window_03 material as an example.

Exported materials consist of two parts: *.json files and *.png texture maps.

• *.json file records the material's metallicity, roughness, self-luminescence and other parameter values, as well as the texture map information used by the material.
• *.png texture maps are various texture maps used in materials, including primary texture maps, self-luminous texture maps, metallic roughness texture maps, normal texture maps, and so on. Materials A variety of visual effects are usually achieved by two parts working together, material color and texture. Take the base color texture map MI_Window_03_BaseTexMap as an example.
• The baseColor color information is recorded in pbrMetallicRoughness of the *.json file.



• The baseColor color texture information is recorded in textureunitstates of the *.json file.
