Reduce the Render Bucket size to minimum (8) and reduce the Ray Depth to 1.
When possible use Shadow mapping as it is not as memory intensive as ray tracing especially when it comes to hair and foliage which are usually heavy in transmaps.
Actually this one is getting less and less true…since 3Delight 10.x came out there have been massive improvements in the raytracer…both memory and speed. With the build of 3Delight in 126.96.36.199 they are close to par. With the build in the latest beta, in some cases the raytracer now wins.
Good suggestions. I tried all of that. The thing that is killing me is the shadowing. Raytraced crashes the program, it will go with deep shadow mapping but doesn’t look as good.
Try a very simple scene with a single item (a sphere primitive works nicely) and raytracing…if it still crashes, then you are probably facing a 3Delight problem, that I believe has been fixed in the build that is included in the beta…
The problem with 32 bit Windows is that it will reserve up to 2 GB of memory for it’s own use (XP, less in Vista and later, but still some). Programs can’t access this reserved amount…that’s what the 3 GB switch in XP Pro is for…limiting XP to only 1 GB reserved and freeing the other gig for programs to use. So while 4 GB may seem like a lot, once you add up the reserved amount and the amount sucked up by an onboard video card, you don’t have 4 GB any more.
