RC2 Distributed Rendering, Affect Shadow/Fog Problem

V-Ray V-Ray for 3ds Max Issues

Hi there,

Have not yet found the time to install RC3. Maybe this bug has allready
been solved ? :sweat_smile:
When reading through the RC3 Fix List, I see that some Affect Shadow
problmes were solved.. but those seem to be different from my problem.
I noticed that my water material renders different on DR machines.

When you look at the water you will notice some buckets that are bright and some are dark. The darker ones were those rendered local while all the brighter buckets come from the DR machines. This only happens when “Affect Shadow” is turned on. Actually when Affect Shadow is turned off
the problem is gone. Also when Affect Shadow is turned on but I disable the fog (default settings) it works well.

cheers,

I have not been able to reproduce that here, but if you have a scene that I can use for testing, it will be helpful.

You can find the scene (lite version) here.
Made with Max 8 and Vray RC2.

Some further Test images.

Without DR .. this is how it should look like.

The same with DR Rendering

With DR “Affect Shadow” turned off

With DR “Affect Shadow” on, Fog turned off

Hope that helps,

cheers,

Yes I encountered the same thing with RC2? (havent tried with RC3) and sent Vlado an email on it. I had gone through and checked all my systems default decimal values.

I think it was related to either Fog or Affect Shadows. Unchecked one of those and it rendered.

I could get the bug to happen in RC2, but not in RC3 and later.
