Hi! my metahuman face mesh imported from unreal to substance painter (following this quick guide https://youtu.be/uaYNgMcEYEE) is broken. I tried different fbx versions, but they all ended up the same.
I haven't tried this workflow before, but from your screenshot, it looks like you have a lot of meshes stacked. It might be the LODs... Have you tried opening the .fbx in maya/blender/max? Thanks a lot, Regards,
