As I mentioned in a few other threads, when you use imagers to denoise individual AOV layers, it may work the first time, but change anything (or sometimes even just render again without changing anything) and it stops working. Then it will work again randomly.
The Renderview always seems to contain the correct Denoised layers, just the rendered EXR doesn't
Might take a few renders to "break" it, but it does break
I've tried this on 3 workstations with the same problem happening
Here is a demonstration.
First I render a simple scene, component AOVs, GPU, Optix denoiser. everything works fine.
Then I change specular to coat and I lose my denoised layers
then I change to * meaning all layers, and again, no denoised layers.
Worked first time as you can see.
Worth noting....the denoised layers ARE present in Renderview.
Can anyone else confirm this?
