Multiple processors

I notice that the Yafray renderer has an option for multiple processors. Does the Blender internal raytracer support multiple processors? If so, does it do so automatically?


Yes and no.

To the complete left of the panels you should see a “Threads” option, bump it up :slight_smile: Makes quite a difference. I havent noticed if there was any point in having a number of threads higher than the number of CPU cores, but I would doubt so, I could be wrong though.

Great, thanks!

Also make sure you’ve got Xparts and Yparts set to values where X times Y is greater than or equal to your number of threads. (I like 4x4 or 8x8 myself). It will break up the image into tiles, and assign one thread to each tile. You’ll never regret having as many cores as you can afford.
