Light splotches

[t3dm]

Hi There,

Doing an interior fly-through which has been rendering fine up until now. Just noticed these light splotches appearing. They don't seem to show up doing the LC pre-calculations but they do appear vividly during the IR pre-caculation

Has anyone came across this before? The model is pretty large and detailed so we're checking all the geometry but as mentioned its been rendering fine up until now.

Thanks in Advance.

does it do when you calculate the frame individualy? without using precalc LC and IRRAD?

yes, it happened.. we found out it was the HDRI we were using for the outside environment though...
