The problem is :
DR renders buckets with slight lighting differences. Not just maps, only colors too.
All machines have 3dsmax 2016 with the latest Vray version installed.
-Checked the gamma settings on all nodes
- Checked the maps on all nodes
- Checked IES files on all nodes
All is fine.
The render nodes are
Intel Xeon E5-2699 v3 @ 2.30ghz 36 core hyperthreaded to 72.64GB of Ram
So anybody can help me?
Hi,
More things to check out:
*) Make sure that the Windows regional settings “Additional settings” “Decimal symbol” and “Digit grouping symbol” have same setup for all machines.
*) Different V-Ray versions installed on the machines could also lead to such issues
Are you able to reproduce it even with a very basic scene setup (no maps) ?
Is it possible to share some images ?
Hi,
Sorry for the late reply. I missed the message. We are still having the problem. I checked all the regional settings and they are exactly the same.
Tomorow I will try to reproduce in a scene without maps.
Thanks once again.
Can you attach an same image so we could see how exactly the buckets looks like?
Have you also checked whether all render nodes have absolutely the same V-Ray version installed?
If there are maps in the scene imported via 3DSMax Bitmap node please update them to use V-Ray HDRI node via the following tool:
There is a bug with Bitmap node which sometimes force Max to load textures with wrong gamma value.
I have the same issue. Strangely, the IR was different from node to node, but the result was the same (was it only a display issue of the IR?)
I checked / UNC / VRay versions / all bitmap inside VRayHDRIs / Regional settings… all correct but still the brightness difference.
Try to uncheck “transfer missing assets” in distributed rendering options.
We have to change the compression method for the IR map DR preview in order to avoid such issues. I assume that the final image is being rendered fine ?
Looks like it renders fine. I’m not 100% sure but I don’t see splotches on flat surfaces where the buckets were really contrasted.
Ah if that is only on preview of irr map than it will render fine , we have it constant here. Was quite surprised with that for the first time , but since final is ok , than looks like it is just preview buckets got from DR nodes are different.
One other thing you could try is turning of Probabilistic Lights…I’ve had nodes render buckets differently with that checkbox enabled.
when i saw this here and there, i also never thought that the final rendering is affected.
as i read this here i did a small test and i think the final render surely is affected, but it quite gets blurred and we can´t really see it easily.
you can measure the difference in the final rendering ! and i would also say you can even see it a bit.
with “transfer missing assets” it went away.
It looks like one or more render nodes have missing texture/s. That’s the reason why Transfer missing maps helps in this case.
Yeah i can confirm that difference of IRRmap buckets in preview window does not affect final render (of course if you do not have any missing textures)
