1st render fast. 2nd and 3rd... Really slow
on May 15, 2009 at 5:38:52 pm

So here's the issue. I'm rendering my scene, with maybe 8 lights, and final gather on, nothing too complex. When I go to do a high quality render for the first time since opening the application, it renders in like, 1:58sec, but if I hit render with the same scene after it finishes, it will take like 18min to render.

When I look at my activity monitor, the first render has all cores running to maximum capacity for the most part. But for every following render, they are sporadically in between full and around 15% roughly.

I'm running:
2 x 2.8 GHz Quad-Core Intel Xeon
16 GB ram
Maya 2009

Are your rendering from Maya itself or batch command line? Maya prefers to be rendered via batch, not from the actual app.

i was doing with just the preview render, but now that i'm doing it with the batch I get consistent, reasonable render times.
