The ambient occlusion for the chin strap under the FlightHelmet shows a couple obvious errors:
- One side has occlusion from the buckle in the wrong location.
- The other side is occluded for most of the surface, but this area would not be occluded. It also has some pixelized artifacts.
Were the UVs misaligned or inverted after baking the occlusion?
