Please disregard my earlier comment. I think I have fixed the problem with internal surfaces on '30585b'. Though I remained the top surfaces under the studs. I assume it's ok in this case? Besides that I have removed and replaced most of the primitives and rearranged the surrounding quads and triangles. Now there is a significant reduction in overall polygons (obviously). I don't even know why chose to have that many primitives in the first placeĀ
