Light cache only runs 4 threads?

[davidr]

Hi. I just got an amazing dual quad-core PC, and noticed that lightcache only uses 4 cores, whereas irrad and rendering use all 8 (and can maybe use more?) I'm curious about this limit and wonder if future Vray or future CPUs (8 + cores) will use all cores (but maybe only on 1 socket?). Thanks.

Set your "number of passes" under the light cache to 8.

Hey, thanks a lot! It works like you said, twice as fast. Thanks again.
