Defines how the mapping coords for a texture are generated.
Real-time applications typically require full UV coordinates, so the use of the AiPostProcessSteps#GEN_UV_COORDS step is highly recommended. It generates proper UV channels for non-UV mapped objects, as long as an accurate description how the mapping should look like (e.g spherical) is given.
