I’ve got a problem at rendering with a huge file of nearly 5 000 000 vertices and 34 lamps. Raytracing is not activated. I use OSA 16, Buffer shadow, Premul, PAL 720 x 576, Fields (sometimes Blender does render Field A and crashes on Field B).
I work under windows XP on a Pentium IV - 3GHz with 2GB of Dual channel DDR Ram.
After checking the 16 OSA samples, The Hard drive swaps a lot and Blender crashes and displays this error message in the console :
Malloc returns nill: len=81938704 in imb_addrectImBuf
It seems to be a problem of memory allocation, but blender displays 1.4 GB of needed RAM. Even if windows XP takes a part of it, I think that the rendering should be done without problem.
I have 3 computers of nearly the same power, and I encounter the problem on each, with various releases of Blender : 2.33a official- 2.34 official -2.33a BlenderIntel -2.34 blenderIntel.
I have to delete a lot of detailed meshes in areas that are not shown by the camera to be able to render.
I have tried to render by parts (2x1; 2x2 ; 3x3; 4x4; 5x5), without solving the problem.
De-Activating OSA avoid crash, but the result is not usable, of course !
I’d like to render my animation (a long walkthrough into a detailed museum) in one time without deleting objects, because I’d like to render when I’m not at home for several days.
Does Blender needs an amount of paginated memory in config.sys ?
Have you got an idea ?
I have to finish my film for an exibition in january, and I’m loosing a lot of time because of those rendering troubles.
Thanks in advance for any help.
