displacement nightmare... 2004-06-25 - By luc froehlicher
Back hi everyone I've been messing around with displacement for 3 days and so far I'm lost. I crash every 15 minutes. with message like this : raylib[1644] MEM 0.2 fatal 031006: cannot free memory I've got 2 Gigs of ram and I never saw my ram usage exceed 800 Megs during a render.
I'm trying to render an object at subdivision level 2 (449 000 triangles) with displacement. the original object was detailled at subd level 4 in zbrush (3.6 millions polys) the initial (modelled) object at level 0 is 14052 triangles.
displacement settings : fine , length 1 , view dependant , sharpness 0 , min0 , max 7
I've tried to tweak the max value , no view dependant , bsp settings , memory settings , using .map , empty all caches .... same crashs.
rendering in sequence is a dead end : first frame ok then hangs batchrender is a little bit better : 5 6 frames then hangs...
I did a test with a 3d texture as displacement and it renders very fine , I managed to render a frame with up to 10 millions triangles so for the moment I suspect the UV's or something. find attached the xsicabs stuffs
any idea is welcome to help me out of this nightmare.
(this is with XSI4.0)
