I've been trying to import object with materials that utilize normal maps and displacement maps (from rhino, materials are vray) and I've run into a few problems.
1. Rhino seems to preview the normal map of a material in rendered mode which causes that map (and only that map) to be imported into an unreal material.
2. When a normal map is imported both the sampler type for the texture sampler, as well as the image compression settings are incorrect. Both need to be fixed in order for the material to display correctly.
3. Displacement maps don't work at all with meshes imported from a .3dm file. Even if I import and set up assets correctly (basically rebuild the material inside unreal), as soon as I apply a displacement map, the material disappears from the mesh and is replace with the default world grid. If I export that same geometry to an fbx file and import, the material will apply to the mesh and displace it.
Since I'm just learning Fabric, my first assumption is always that I've missed something. Are others aware of these issues? Did I in fact miss something? Am I able to correct these issues with an import pattern?
