I'm running some quick glass test at the moment for a future piece.
I have been attempting to bring in a model from lightwave ( a Martini glass) this has a duplicated mesh with an outer surface and an inner surface i.e a glass duplicate mesh with flipped normals.
I was hoping that this would give me an improved refraction render quality by faking refraction "thickness" but I can see no difference even if I hide the flipped poly mesh in the test renders.
Does Carrara correct imported normals - I couldn't find a way to double check the normal directions in the vertex room.
Anyone with any knowledge on these kind of specifics please help a p'or boy.
I'm most probably am going about things the wrong way
