MDLMaterialSemantic.emission
The color emitted as radiance from a material’s surface.
Declaration
case emissionDiscussion
A renderer (or other software component processing the material) might not treat the emission channel of a material as a light source illuminating the scene. Instead, an emission channel prevents affected areas of a surface from being darkened by other aspects of lighting and shading.
Model I/O uses this semantic for the Ka and map_Ka attributes when importing from the MTL file format (for assets in the OBJ file format).
