max question thats kinda n00bish

DaAan

i feel so dumb askin this since ive been using max for about 7 years now but.. im using vRay 1.5.something, and the scene im rendering (and its happened before) but i get these funky coloured dots when ive used GI and some times when i dont use GI too, but ive always used LightTracer as my advanced lighting solution and i cant seem to get rid of these annoying green artefacts.. so a lil help if possible would be greatly appriciated.

cheers
