Use Rhino.Inside to export fbx with materials AND textures embedded?

I’m having trouble using the vanilla Revit fbx exporter as well as the legacy Twinmotion fbx exporter to produce an fbx that has both materials and textures embedded. My target software is Unity.
Does anyone have experience building out something with Rhino.Inside for grasshopper to setup an fbx export with extra options such as what to embed in the file?
