I have some problem with background pictures when I use firefly rendering. I import a background pictures and when I go in Materials room on bakground objects I have some nodes as BG picture, BG color, BG movie, Black and BG picture is not connected. I connect it delete the other nodes and and come back in my sce,if I come back in materials room again I can see all nodes just like before and my picture is not connected... If I make a render my background is white!!! I have not this problem with P4 rendering but the problem is the resolution of the background...very bad... Is any have a solution for this problem... THX
