Jaager, it's almost certain 3rdeye had both white eyeballs and white eyewhites when 3rdeye exported it from Poser. This demonstrates the vast difference in the way Poser and Carrara handle transparency. Poser does it intuitively, but Carrara does it according to the laws of optics. If you search this forum for Antoine Clappier's discussion of transparency, that should help in handling the eyeball problem. My approach is a shortcut - just delete the eyeball material and forget about it - no more worries.
