Multithread rendering problem

Hi!

I've been using KT for some time without any problems, but recently I've encountered a strange issue. When I render using progressive methods, the program hangs after first pass. It stops showing 99% (sometimes 100, sometimes less) and that reported number of threads is being decreased by one. When I try to make small resolution test (300x200 pix) it sometimes works properly, sometimes it doesn't (usually it doesn't).

I have big model (outdor with plants etc). It's all about 2GB. I've tried on two computers (win7 8GB RAM 8 threads, win8 16GB RAM 12 threads), using path tracing progressive and MLT.

Update:
When I do one core rendering I get error at the end of first pass - it reaches 100% and when it is supposed to start second pass an error appears.

Thanks

Re: Multithread rendering problem

I presume you have the 64bit version of KT installed? If not, it doesn't matter how much ram your computer has, in 32bits it's limited to about 3Gb of RAM.

This sounds like a RAM issue. You need to make the model smaller - likely you have very high-res textures that do not need to be so high resolution.
