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.

scrappy 08-09-2008 09:56 PM

hey man,

is that in the render settings tab, if you could explain a little more?? iam a noob you see lol.

cheers

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.

scrappy 08-09-2008 10:21 PM

ok ill try that, and thnks dude. ill get back to you and let you know.

cheers

scrappy 08-09-2008 11:43 PM

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

scrappy 09-09-2008 12:14 AM

do you mean the instensity? or am i looking in the wrong place?

honestdom 09-09-2008 12:37 AM

yeah the intensity, i think the defaut is about 50k.

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.

thanks guys your being really helpful,this is the first time ever i have had to deal with FG and GI. but once these light emitions are sorted, will my render look crisp and clean?

GecT, love your work, i can tell you deal with lighting alot, keep up the good work man!! and thanks for the tip with my screen shot lol

only one way to find out! render that biatch! (but in a smaller resolution so it won't take as long to find out...)
