Hello,
I'm rendering an interior office scene and I'm having trouble with Vray Light sampling subdivs.
We are using Max 2020 and Vray 3.70.01
I have tried to optimize my scene by using higher sampling in my lights to get vray to ease up on the AA. When rendering the animation I use IR and LC in the normal way you would (calculate LC, use the LC when calculating the IR and finally render using the IR).
I have 4 images for reference, 2 are from a single frame rendered on my pc using IR and LC set to a single frame, diffuse and sample rate channels. The other two I have a screenshot from one of our render nodes rendering the image using IR prepass files.
As you can see in the photos the image that is rendered using prepass and backburner has a lot more noise and the AA sample rate is through the roof.
I have never encountered a problem like this, I have added screenshots of my settings as there is possibly something I have overlooked or mistakes I have done in the process.
I tried to import the whole scene into a new scene to see what would happen, but the results were largely the same.
Can anyone help me identify why this is happening and how to fix it when using prepass.
I rendered a sequence yesterday with the GI set to single frame, so every frame rendered it's own IR and LC (this had a lot of flickering as you can imagine), but the average render time was 11 min, I tried to do the same with the same setting, but using prepass, estimated 10h per frame....
I couldn't find someone with a similar problem while searching if someone has encountered this and found a way to fix it I would be grateful if you could send me in the right direction.
Thanks.
Edit: I mistakenly posted this in the wrong place, would it be possible for a moderator to move it to the issues section?
