Hey guys,

iam having a problem trying to get my render sorted, i've had a play with the FG and GI for days now and for some reason the light emitions or the FG are leaving these unwanted bolch's, i've raised the GI options/Radius up to a very high count,but still no joy.

can anyone save me from this pain!!

Thanks.

looks like your interpolations in GI are too low.

i'm a noob too, ok i've hada look in maya and made a simple GI thing... from what you said try reducing the radius to 0 and just increase the photons on the light.

shouldn't the number of photons be around 100k?

The default photon intensity on a light is 8,000, GI Illum photons are 10,000 I think. The photon intensity on the light seems really low but then again I don't know what you had set the GI scale to. I think the problem is the GI Radius. I see you have FG checked also, can't see the settings there, it could be fighting you're GI settings. Also I see you had to grayscale your screenshot to get it under 200k lol :p, if you have Photoshop, Go to File, go to that save for web and devices option, hit that lil arrow (see the pic), choose optimize to file size and enter whatever number and voila. Really handy.
