Hi there

This I've never seen in my life and I do render with several render engines Not sure why you are have there transparency set at 2.0,when you don't have there any map,can you try to render with transparency set at 0 and that model C-Tunic for V4 do have maps if yes can you try plug there transparency map from C-Tunic if there is or can you post the link on that model

Thanks,Jura
