Thanks for all the confirmations.
I have logged this with the Foundry but they can't reproduce it yet.

Cheers,

Hi there!

Got this here as well. Solution is quite easy: just add a FrameHold node before 
the Grain input of F_Regrain, so every frame grabs the grain from the same 
source image.

But yes, something like the "Lock Noise Analysis" button in the Denoise node 
would also be very helpful in the F_Regrain node.

Hi all,

this is reported but was wondering if I'm the only one who finds F_Regrain 
close to unusable in a render farm environment?

It's all dandy as long as you render locally, but as soon as you have multiple 
machines render a script with F_Regrain in it, some of the frame batches are 
all screwed up with completely wrong grain (way to big and intense - confetti 
like).
It seems like F_Regrain samples it grain again when the batch starts or 
something. I'm rendering on linux and osx, workstation is linux.

Does anybody know what I'm talking about? Maybe even a solution to fixing it? I 
will generate a grain plate locally now and use that on the render farm for now.



Cheers,
frank
