Dark buckets

[gagui]

I've installed last nightly version and my problem seems to be fixed.
Thanks!

I am still having the issue on this one. I know Vlado was looking into it, but I haven't heard back. I sent the file a month ago.

[glorybound]

Nothing I do will get rid of the errors on the image. I sent the files over a month ago, but I have not heard back. I am going to try non-GPU, but my render times explode; that might be what it takes to get this one out the door.

[glorybound]

How do I get nightly? I can't render these images out, so I need a solution.

[MANUEL_MOUSIOL]

glorybound you can request it at support.

But I have to say I'm on the latest nightly and have s similar problem.
I thought it was the cpu in hybrid mode but bucket like differences are still there even when rendering without cpu .
Testing with only 2080 tis and leaving the 1080 ti out .
I'll send a scene as soon as possible.

I noticed that this doesn't appear in IPR mode and but with progressive and light cache .I think I succeeded in getting rid of the bucket like differences by switching to Brute force . But rendering times were obviously horrible...

[glorybound]

I have tried everything and absolutely nothing is working. I sent the model a month ago, but I have not heard back, except the problem has possibly been fixed. I am tempted to give Corona a try just to get this job done.

[MANUEL_MOUSIOL]

For me switching to Brute force solved it.
i find it strange that lc produces bucket like artifacts.
So you even have it with brute force on?

Btw I also noticed that my windows have no reflection...not even in the reflection pass. Why is that? And how to solve it?

[glorybound]

Yeah, I brought up the reflection issue when NEXT first came out, but I don't think it was acknowledged on the forum. I end up uses a RAW Reflection pass. BF, I think I tried, but when I saw a 7hour render time, I just canceled it.

[MANUEL_MOUSIOL]

I thought there was no raw reflection pass?

[glorybound]

I am trying BF, however, it doesn't look good, so far. 1/2 resolution is taking 2X longer and I am still seeing a ton of white dots. I am going to let it run; so far only 10 minutes into it. Is this the issue that you are having?

[MANUEL_MOUSIOL]

no, mine look like big buckets that have different exposure or so. see on the right of the sofa on the attached image. it is denoised and a test rendering though. there were more artifacts and lines and different brightness levels at different places.
yours look like fireflies and places with different noise levels... so, different problem I guess...

[glorybound]

Do you have the WIP thing checked in your V-Ray Dome? That causes those for me, so I always have to uncheck it.

[MANUEL_MOUSIOL]

Really? Shit, totally forgot about that and that it might cause problems. I'll check . Thanks!

[glorybound]

BF + 1 hour = still one hell of a mess.

Just to clarify, I know the issue, it's my IES lights. The Revit model came with dozens of IES lights with IES files, all specific to the project's suppliers. My client wants these to be used, however, I can't. If I turn them all off and just have the V-Ray Light material on the light lens, everything is fine. Is there a known issue with IES lights and files? Is there something I can do?
