Insert material processing in workflow Tests and experiments with unknown values Reviewed material resolution The first approach of model constructor optimize vertices/indices numbers but doesn't support correctly texture coordinates. Raw approach output good result but need advanced functions in obj lib to efficiently store vertices, textures coord and indices together.
