This has currently following limitations: Each property has multiple strings, only one should be used (preferably the first), Specular/Metallic map's alpha channel maps to smoothness (inverse roughness). Writing importer plugins for assimp is considerably easy, as the whole postprocessing infrastructure is available and does much of the work for you. a pull request with your changes against the main repository's master branch. Pretty much all PBR workflows involve having them merged into a single texture, to reduce texture lookups. If the docs don't solve your problem, ask on StackOverflow. E.g.
