Lots of bug in this version. Causing productivity to drop drastically. Not only does the depth of field cause the program to crash, but now every shot in the Shot Manager is green.
Mac 10.10.5 using NVIDIA GeForce GT 740 0 MB graphics card.
To be clear, when you say "in this version", do you mean 3.6.0.22, or 3.6 in general, or...? If you do mean 3.6.0.22 specifically, you could try rolling back to a previous version to verify that the problems go away, unless you bought FrameForge 3.6 very recently.
We know about a bug in the driver for NVIDIA GeForce GT cards that cause depth of field to crash if on-screen antialiasing was enabled. But in response to that, we made FrameForge automatically disable on-screen antialiasing on such machines. So it's surprising that there would still be a problem with depth of field.
The bit about the green-tinged shots is totally new to me. If you create a new empty previz project, drop in an actor, and snap a shot, does the shot look green?
