Re: viz 2008 - multi-threading
There was some discussion about this in the past, and from what I remember, VIZ is only 32bit, so unless you buy MAX, you aren't going to get true multi-treaded performance.
However, Mental Ray and Radiosity (or Advanced Lighting) should use all your processors. If you are doing a regular scan-line render, you might not see more than two...

Re: viz 2008 - multi-threading
hmm...guess either have to wait for the x64bit version or upgrade to max
did a test render using Mental Ray and it only shows 3 threads. so i guess it is really limited to that since it's 32-bit |

Re: viz 2008 - multi-threading
No, 32-bit OSes and apps can support 4 CPUs if they so desire. That's not what's causing the problem (though I couldn't tell you what is, not knowing anything about Viz 2008...)
