Hello,

I am working on a wedge tool (that flipbooks the results too). I noticed that the "denoise if needed" doesn't work when you fetch the flipbook ROP using the ROP fetch top. Interestingly, it will work if you set the cook type to "In-process", but why does it not work in Out-of-process? My guess is it has to do something with the fact it's being processed by a headless process in the background? If you look at the photos below, first image is hitting render on the flipbook rop and it looks normal. The second image is that rop being fetched in a topnet and it's not being denoised. I also included the hip file. The noise isn't horrible in this example, but it can be pretty bad in some of my tests.

Thanks
