Trying to import a character model with facial blend shapes. Original pipeline: hi-poly from Zbrush-> low-poly w/rig, weights and blends in blender → FBX export → import into UE4 as skeletal mesh.
In the attached image on the left is the character with no facial blends and a low poly face, on the right is the higher poly head with facial blends.
I get a strange shadow, no clue what is causing this.
