Hi Drawfun,
Sorry for not responding sooner, this kinda got down the rabbit hole. Per your request I started removing things and testing the new window option with denoising. I discovered that it was only when the spider's legs were included that there were issues. I did several tests one by one, eliminating things like the hair particle systems, and doing the polygon clean up tools in edit mode. Nothing worked so I went on to looking at the modifier stack. I noticed that the legs had a subdivide modifier applied to them, and I checked to see if OpenSubDIv was enabled on the Octane settings. It was and when I turned it off, the denoiser worked great.
So it appears to be an issue with OpenSubDiv or some other related issue. Hope this helps. I tried to make a simple example file to upload, but I couldn't replicate the issue.
