After exporting from blender with smooth faces on and my sharp edges marked, the flat area gets populated with triangles and becomes warped. Ive tried just about everything i can think of, but it always looks the same.
Above Image:
Same model but the left was exported with no smoothing groups and the right was exported with smooth faces. Ive also tried smooth edges, but it gives the same issue.
Above Image:
In blender the one on the left shows the model in edit mode with the area populated by normal faces, on the right is the same model in object mode showing the area with no geometry.
When in UE4, both versions of the model show the area populated by triangles but only the one with smoothing has the warp looking triangles. Any idea what is causing the warped look and how to fix it?
Thanks in advance!
