Fix the sky in one of the levels in virtua on. The problem was caused by the fact we didn't split the mesh by the fog % burn through, so all the polys had the same value. We could use a vertex attrib, but % burn through fog is so rarely used and when it is, normally every poly in the mesh has the same value.
