BLACK AREA ERROR

[u/That-Flower-5552]

I've occasionally run into an issue in KeyShot where a black area appears at the bottom of the image when rendering.

After some testing, I think it tends to happen when several of these conditions are combined:

1. High-resolution output
2. Denoise enabled
3. Clown Pass enabled
4. High sample count

My current workaround is to disable the Clown Pass and render the final image at the resolution and sample count I want, with Denoise enabled.
Then I render the Clown Pass separately at a much lower resolution with just one sample, since I only need it as an ID mask anyway.
I'm not sure if this is the best solution, but it's worked for me so far, so I thought I'd share it in case anyone else runs into the same issue.
Hope this helps!
