Question about denoiser and progressive rendering

[jstrob]

I want to try to use the progressive rendering to render an animation with the denoiser.

But since I'm rendering on my render farm I don't want to use a fixed time for the progressive sampler.

My question is: if I set the progressive render time to zero, will it eventually stop when it reaches the noise treshold? I'm rendering a frame right now and I notice the denoiser is denoising multiple times and I don't even know when it will stop. Why is it denoising multiple times? Normally I use the bucket and the denoiser is applied only once.

Ok I found the answer, I had to set the denoiser progressive update or something like this to 1 instead of 10.
