Hey all,

I forgot what setting I need to tweak in order make the shadow area cleaner. Any tips??

Thanks,

I don't render in Carrara, but it looks like GI splotches. You might try to increase your quality/accuracy of your lights and shadows...

Just need to turn OFF(uncheck) "Interpolation" in the render tab under Global Illumination.
Turning up the precision doesn't help.

Really? That doesn't even sound logical. The purpose of interpolation is to make more smoother blends between GI sample points. So I would think that turning it on should help remove the blotchiness... If what you said is correct, then it sounds like Carrara's got it backwards!

my statement was probably too general. turning off interpolation, sometimes works, depending on the HDR you are using... Just because it is an HDR file does not mean that is has a dynamic range.

for some reason, in Carrara, bumping up the precision doesn't really help... Although it will in some circumstances, but most times, i get a smother render, with it turned off altogether.
