vray light material

any ideas on why an object with the vraylight material applied to it will not “light” it just stays dark

weird…

oops

sorry, wrong topic, oops

Will answer anyways. You got GI on ? The VRayLightMtl only emits GI, no direct light.

live and learn

figured it out, secondary ray bias was 0, apparently this cannot work, made it .01 and they popped

problem solved, thanks

wich means you most likely got co-planar faces in there, wich is un-desirable

thought i

did too but apparently i dont…

?

gonna try to see if the vray light material works in a blank scene without secondary ray bias on
