VRay Dirt & lights

V-Ray for 3ds Max V-Ray for 3ds Max :: Issues

Hello,

I’m pretty sure it has already been reported, but since I can’t find a thread about that, here we go again :slight_smile:
Would there be a way to exclude VRay lights from Dirt calculations ? I’ve tried with Result Affect, but apparently, it’s impossible to select lights (or a named selection sets including lights) … any idea, please ?

Thanks in advance !

Turn on “work with transparency” in the dirt map!

Ah thanks for the suggestion ! I’ll try this for the next rendering :slight_smile:
But what does “transparency” have to do with lights ? not very explicit to me.

4

It’ll take into account the “invisible” setting of lights.

5

ok, that “somehow” makes sense :wink: Maybe worth making a note about that in the manual …

Thanks again.

Yes, will make a note about it.

Best regards,
Vlado

Thank you, Mark, for this addition to the manual. This information is important enough to be mentioned I guess, thus avoiding useless posts in there :wink:

Cheers.
