My money's on the FBX export settings, and the import settings to UE4 as well, potentially. Look at some Maya-to-UE4 documentation to see what settings are and are not recommended for exporting; and also, what import settings are recommended in UE4 for this type of mesh. This section of the documentation addresses a lot,…
That's the thing. The normals are all pointing in the right direction. I've done a bunch of work on another mesh, and the issue arose again. I'm pretty sure it's happening because I welded vertices together around a seam, which throws UE4 for a loop. Is there a way to re-split vertices, like some sort of export option?…
I finally figured out what was wrong with my mesh, when exporting it as FBX and punting it into UE4. I'm so close, but have hit a snag. The normals are screwed for the top half of the head mesh, where its split and the vertices are doubled. Or at least, I assume so, since the issue with the mesh in game looks just like an…
