Does anyone have suggestions in regards to extending the FBX importer to allow further customization to imported models and Materials? For example can we hook into a postprocess materials, postprocess models event through blueprint, or through C++?
Currently, the limitation of importing materials is that unreal only imports the diffuse map and normal map of the model. Defined here (https://docs.unrealengine.com/latest/INT/Engine/Content/FBX/Materials/index.html)
However, I would like to extend it so that it also imports the roughness map, and connects specific channels with specific inputs of the material. This way I could customize the whole material creation process to fit my needs.
Any ideas, suggestions?
