Title: GI full render bug 1.9.88.1
Post by: PG on May 01, 2008, 03:16:22 PM
I got this error on my wheat field render using the new version 1.9.88.1, it works fine if I get rid of GI or do a quick render but if I do a full render with GI enabled this happens.

Have you tried lowering your thread usage to two maximum?

This is most likely a memory-related error and is probably caused by the multithreading, which increases memory use fairly significantly over previous versons. Rendering with a single thread ought to work if it did so in previous versions. You might be able to use 2 threads as well, if you're currently using 4 (quad core).

To limit the renderer to a certain number of threads, go to the Renderer settings panel, to the More Settings tab and set Maximum Threads to 2 (or the desired number).

I found success by putting 1 in the Minimum and 2 in the Maximum.  Still faster than before, even with transparency.  I'll experiment more to see if I can push the upper to more than 2 and how much more.  Since this is a memory issue, 2 might be my max.

I do also experience this often, in many cases restarting the program will help. I use a quadcore with min. 4 and max. 16 threads.

Thank you Oshyan for the information, as I have the same bugs. I'll try this.  ;)
