Hello Everybody, for some reason our refractive objects get strange bright buckets, so it looks like this: There are just some rect lights in the scene, nothing special, IM+LC as GI. We did not use distributed rendering in this case. The problem is that we can’t reproduce it and it looks differen…

that reminds me of my second problem in this topic - Chaos Forums For now, I couldn’t find a solution. Support is looking into it. All my test scenes render fine with Vray2.4 (whatever Maya version) but have bad buckets with Vray3.0, DR + “Use Local Mach…

All your machines are running exact same vray version? Also does it look correct with using brute force?

Guys, thank you, in this case it is not a Distributed Rendering related issue, both images were rendered locally. We will try render it with brute force, but it’s just a workaround, not a solution, because we actually use IM+LC most of the time. @waaazoo We have the same problem with distributed …

I understand the question of Dmitry. Using Brute force is more to see if it’s LC or Irrmap which cause the problem. You can try to make these tests which were suggested by support: 1- IrrMap (primary) + BF (secondary) 2- LC (primary) + BF (secondary) 3- IrrMap (primary) + none (secondary) 4- L…

Hello everybody, unfortunatly it is not caused by GI. I tested it with default settings (no GI!) the result is still very strange. Same machine, same scene, the same time but we get different images: But now we can at least reproduce it and I’ll send the test scene direct to chaos group support. …

Hello Zdravko, thank you for your reply, i have already send you the scene using my company e-mail (this is why you probably can’t track it). The support says that it was fixed in the latest nightly build. Since the problem is very critical, it looks like we have to switch to nightly build everywhe…

Yes, we use Deterministic Monte Carlo. I am glad you found a workaround, I’ll keep it in mind in case someone else show up with the same issue.

That doesn’t mean “bug free” :slight_smile: Best regards, Vlado

I’m glad I found this thread. I’m working on a piece of sheer cloth, it has a bit of thickness, so that refractions may work properly. I can confirm that I was getting artifacts like inconsistent buckets the moment I had any amount of refraction. The BRDF model was Ward(VrayMtl). If I switch to Blin…

The result looks strange. It will be best to send us a scene so we could have a look.

How to mass-convert to Vray Materials.... any idea of good script ?
