Very bad bug with lights !

[Dariusz Makowski (Dadal)]

Heya

Soo well I finally give up and decided to report it. Its definitly vray/standard light bug...

I'm guessing the shadow cut off is too low and my scene is exploding with artefact's

Funny thing is Vray-RT-CPU works perfectly

Vray lights dont have that issue, only standard and maybe photometric....

Anyway screen below.



Any chance for a quick fix ?

Thanx, bye.

Do you have any more info? I don't understand whats actually going wrong?
Are you using standard max lights with Vray shadows or Bitmap shadows?

[DanielBrew]

When you say standard light do you mean the standard omni?

Also, what are your AA settings?

[Dariusz Makowski (Dadal)]

Look at shadow fallof, with RT is smooth, with production its sharp, edgy.

Im using spot/omni/etc etc standard max light

Shadows are Vray SHadows/area shadow /mixed sizes

AA is irrelevant


Anyway, finish image here http://www.chaosgroup.com/forums/vbu...here-and-there

What sort of materials are you using? I looks like it could be caused by reflection cutoff being set too high.

Nice images on your link btw.

[Dariusz Makowski (Dadal)]

Its not reflection, its shadow, its vray eeee car paint I believe, which is at 0.001 if I'm not wrong with cut off. If I put a Vray light in that same spot I can get that same smooth effects as RT in production ender.

Thanx

Ok then; can you get us just that part of the scene with the problems to vray@chaosgroup.com so that we can look at it? I don't need the entire geometry, just the part where the problems are.

Best regards,
Vlado
