Hi all

Seems to not load the denoiser in any render version (render window, mpley or "to disk"). Any ideas? Do I need to relink something?

Thank you

My first thought, Karma or Mantra, second thought, has it ever worked on your current system's hardware?

Are you using a GPU that supports denoising......according to "support"
The OptiX Denoiser requires a Kepler or later NVIDIA GPU (K, P, M, V prefixes).

I haven't got an AMD GPU, does the current version of Houdini denoise works with them or not I don't know.
Though I imagine it's unlikely NVidia's Optix denoise will work with an AMD GPUs but perhaps Intels OIDN does?
