Inconsistent render on renderfarm

[jop]

Hi,

I have some brightness inconsistency from frame to frame on renderfarm.
Not a texture gamma issue.

Comparing frame/node, it appears that intel xeon vs amd threadripper produce different results.

Using max 2019 with Corona 5.

Have to take some time to setup a test scene.

Hi,

We are aware that there can be some differences rendering on different CPU architectures. It looks like something similar was reported here: https://forum.corona-renderer.com/index.php?topic=26069.msg155463#msg155463

It would still be helpful if you could send over a testing scene and some screenshots if you are able to.

Thanks,

Rowan

Here are 2 screenshots too.
Intel seems to produce more artefacts.

What exactly do you mean by a render farm? Your own local render farm, or an external render farm service?

My own

Hi Rowan,

Do you have some good news ?

Hi,

So the good news is that we now know what is causing the problem.
It is with the dev team and they are looking into a fix for it, but as usual I can't give you a timescale.

Thanks,
