Hi, do you guys think camera blur affects radiosity calculations?

What I mean is:  if I want a final quality render with blurred camera AND
2-pass radiosity, will the radiosity cache from the first pass (without
camera blur) compromise the final quality?  I know it does with different
resolutions, so I was wondering if anyone knows before I get a severe
letdown on a severely slow render... :)

   From my experience, I think you can leave out the focal blur on the first
pass safely. I never use it on the first pass and didn't notice any problem
ever.

Thank you, Jaime.  I think your experience is enough insurance for any
povver. :)
