I have calculated my irr map and light cache at 1024. When I increase the resolution for a final rendering, it estimates like 20+ hours and for the last 6 times just crashed. I have searched the forum trying to find what setting to use but nothing seems to work.
As of now I have the file rendering to a vray image. no frame buffer. The irr setting I have switched to -5 -3 in the min max settings. For the displacement rollout I have increased the edge legnth to 20 and the max subdivs to 128.
all materials have no more than 12 in the reflect/refract. There is some glossy setting on the floor but it’s not much. Under the settings rollout the dynamic mem is set to 900. HELP!
I need to deliver this image to a client and as of now I am at a loss.
well… at 4K you’re exceeding what max can reliably handle in the frame buffer. At this point you need to look into strip rendering with backburner, or moving to 64bit Max 9.
On a more usefull note, you calced the IR at 1024, but your rendering at 4k. I thought the general rule was no more than double the res for using a smaller IR map.
Going so much high may well be causing a slowness due to the significantly smaller IR map… perhaps..
It really depends on what is causing the slowdown; since you have already precalculated the GI maps, the reason for the slowdown could be either displacements or textures. Since your edge length is already high enough, and the displacement should not be a problem ideally, that leaves only textures.
If you have the bitmap pager ON, you can try turning it OFF or playing with its settings and see if it helps.
