hi everyone and happy new year!

workin on a thesis project ... :( using maya to create football robot animations (like FOX tv) to be used during our university football games on a huge 30ft screen outside.....just to fill everyone in.

i noticed when i switched my scene/objects to global illumination, i did a snapshot render of my scene. it took a while longer than usual. i'm worried that if i have this going for a multiple character animation that we're talkin super long rendering times. What do you all think? twice as long to render?

Thanks
Peter

Twice as long? That would be incredibly fast. IME, GI algorithms increase render time more in the magnitude of 5-50 times.

I'd agree with Stew... render times really multiply. Investigate Baked GI or Ambient Occlusion rather than per-frame brute force GI if you want to look for faster 'fakeosity' methods.
