ehtyeci Posted July 20, 2018 Share Posted July 20, 2018 Cubemaps are almost exclusively synced with surface normals. You can manipulate the way the reflection distorts by applying normal maps to the surface. An inverted cubemap is often a sign of backfacing, eg. you're seeing the backside of the surface with the normals pointing inwards. If the glasses are just a single sheet of geometry with the Two Sided flag enabled in the nif or material, it would be pretty easy to miss.

When I swapped back the normals to the vanilla version the cubemap reflection has a similar direction on both glasses when you pan around it. The custom ones I made resulted in the circular effect. Didn't realize normals would affect cubemap rendering in other ways than they work with diffuse maps, so thanks for that! Link to comment Share on other sites More sharing options...
