Operating system and graphics card
MacOS High Sierra Version 10.13.2 (17C88)
Short description of error
The denoiser (whether I use clamping settings or not) goes through the render motions, but then produces an all-black screen.
Exact steps for others to reproduce the error
please see attachments. I simply checked the "Denoising" checkbox before clicking the "Render Image" pull down selection.
Thank you for your assistance with this!
