I have 5 graphic cards at home, and 1 at work.
The home system has 2 GTX Titans(6gb) , 1 980 Ti (6gb), 1 GTX 680 (2gb), and 1 gtx 780 ti (3gb). The work system is a GTX 780 6gb.
I set up the scene at work and it previews and renders fine (albeit slower than at home), When I take it home, it previews fine, but when it renders, the file it saves don't look the same as the preview. Any idea what could cause that? I've included pictures of the preview which has a light blue gradient in portions, and the actual render, which is almost flat blue. The preview looks better than the render.
