I found a great renderfarm, I make a tutorial about that next week.
We have been playing with settings like 2 weeks with them and yesterday I finally got myself inside and start rendering tests.
First of all, here is the test render that I made with my own RTX 2070 Super:
no motion blur, 250 samples, rendertime 1 min 20 sec / frame.
Light setup is explained here:
So my renderfarm machine was like this:
First of all I disabled these:
I learned this from test in another renderfarm: https://irendering.net/
But in this new renderfarm I am talking about here, they had Nvidia 512 game driver, not the Studio. I tried to update it to studio version but no success.
First render, with the same 250 samples settings came out like this:
My main issue / question is that why there is so much more noise?
Then I raised the render settings to this:
Samples per pixer per iteration (useful for multi-GPU): 800
Motion blur / Subframes per frame: 10
This should basically give a noise free render, but no:
You can still see there is some noise, specially at her skin. Something to do with SSS maybe?
Finally, I rendered with same settings this 3K & Simple fog:
Its so clean!
Ok Nvidia rendering gurus… Can you help me to solve out the noise issues at this renderfarm? Do I send you this scene?
