Denoiser refuses to stay off. Each time I alter something it switches itself back on, both if I use the eye toggle and if I turn off ‘calculate’.
Can this be a permanent toggle please?

Try disabling the “Autoswitch to effectsResult” (Settings>System) and see if that makes any difference.

Yes this is IPR and turning off autoswitch has no effect.

This happens in Maya also. Would love a way to control it.
