Thank you for fixing this, and thank you for the Denoiser filter too!
I've noticed Denoiser makes its job better in ImageFilter NE and when we apply in log space. So by working in linear light, it's better a lin2log operation before applying this filter.
The double PixelFilter trick is clever!
Gerardo, could you please post a scene or a screenshot of a basic setup for Denoiser ?
Every time I tried to connect Denoiser to the Image Filter Color input, Layout crashes
