Can anyone tell me what causes these sparly looking artifacts (circled in yellow)? I've got anti aliasing set to a middle range and the area lights are set to 10.

Thanks

How is it textured? Can you increase the reflection / refraction samples? or surface samples? Is it a refraction blur quality?

Hey mummyman, sorry for the delayed response. I'll check your response and re post. I had to launch the render as is to meet the deadline and don't want to stop it. Not a show stopper but something to learn the cause of for the future. Thanks for responding.

If you're using radiosity, do you have Limit Dynamic Range checked?

I have to wait for the current frame to finish. Should it not be if it is (LDR)?

Thanks

I have renders that exhibited similar (if not identical) artifacts when Limit Dynamic Range was unchecked. Though, I suppose it may be attributed to the HDR image I was using as a radiosity background.

Just figured I'd throw it in the ring and see where it lands...

Thanks, I just shut down the render to check. At this point in "might be" the wrong thing to do in case there's a hit in the look. I'll do a test though so I know for future reference. Thanks.

Yes it was unchecked. I checked it and am running a test. Thanks.

I'll be damned, that was it. I owe you a beer. Thanks Rudy! There's a pretty good explanation why in this LW e-book on Pg. 263

Thanks Again! You Rock!

Glad I could help. It doesn't happen often, but (I recall madno on one of the other threads saying) "even a blind squirrel finds a nut once in a while."
