I'm having a problem with two sided texturing. I've applied two materials to the lid of a box, set one two front and the other two back. With Enhanced OpenGL switched on, they show up correctly in the viewport; but only the first one actually shows in the render. I've tried Standard & Physical renders.
I'm using r14. As usual there's a client/deadline breathing down my neck and I'm furiously googling and reading the manual, but any help would be extremely appreciated! I can provide more details if useful.
