@TomReynoldsTG In Daz you can set the start iteration of the post denoiser. For this one it started after 8 iterations, it's the default setting. I don't know how the denoiser was trained or made for, but it denoises all in the scene.
This was just a test render with my new nvidia grafics card. Rendering time was 40 minutes with 3200 iterations and post denoising. I think I'm pretty happy with that x3
