Quote - Every time we get into a GC understanding discussion, the person I'm dealing with goes off and does hour-long renders. You don't need to do that. Is that what you're doing? While I was waiting for a response, I did 30 renders with GC off, GC=1 and GC=2.2. Want to see some?

Heh, no I wasn't doing hour-long renders. I did a couple of test renders very early this evening (probably about 3 hours ago) before you posted in this topic, and the test renders only took me about 10 minutes at half-size- I was adjusting my lights after dropping the GC in Render Settings down to 1.

In my opinion, they turned out rather nicely- will post one after I shrink it down (3000px is a wee bit big for forums) And after I postworked them, I've been banging my head against Photoshop, trying - and failing - to paint fire.

Your example renders highlight the difference in the settings very clearly. Thankyou :)
