Most of the time, I get the hangup on the "Loading Textures"; sometimes it will start rendering then just quit if the scene has multiple figures. Turning off bump maps didn't seem to have any effect when rendering with the P4 engine. I always know when it has crashed and not just being slow when the render preview clears everything but the background color, and it won't cancel (then I have to give it the "three finger salute" to kill it). Once in a while, but rare, I will get the actual "out of memory" message. I use the DAZ high res skin textures quite a bit, so I'm sure that isn't helping if they are overwhelming the buffer, but the weird thing is, I never had these kind of problems with the same figure in 4.03 that I get in 6.0 using the P4 engine. I chalked it up to the memory bug in 6, but I don't know if this is the exact cause or not. Possibly very dumb question: How do you turn off bump maps when rendering with FireFly? I use the P4 engine most of the time (I upgraded from P4) so I'm not really familiar with Firefly.
