MR Final gathering issue

#1

Hi!

I made my first scene on maya 2012 (i was working on maya 2009 until then), and I have a problem with final gathering. When I do my global illumination, it’s ok, photons works well but when i add the FG i have dirty spots everywhere and just can’t find out where is the problem.

I have activated the importons etc… and still can’t find out what’s the matter.
Do you know how i can resolve this?

I’m using some areaLights

Thanks for your help!

Increase the point interpolation of the FG. Should blend out those blotches.

#3

If the result before was pretty smooth and using FG now is suddenly splotchy, interpolation could be the problem, or you have something aggravating the FG result. (Possibly the hot-white light fixtures in the interior)

Increase the filter on FG to 1 (I tend to leave this at “1” by default)

This rather looks to me like you’re not using portal lights for your windows. If you’re using the sun/sky, and doing an interior shot, you’re gonna want to use portal lights. Look it up in the Maya help docs.
