Under the Render tab->Sampling->Denoising I can select what type of denoising to use for the render and viewport. In the tooltip it says whatever setting I select here, e.g. Optix, will also be used in the render passes which I assume is used with the denoise node under the compositor?
In the denoise setting do I have to tick the Render box for the type of denoise to be active or is selecting a denoiser from the dropdown enough?
Selecting a denoiser to use without having ticked the Render check box
What’s the difference between using either the denoiser render setting or the denoiser node? I understand using the node denoises the image at the end as a seperate pass but how does this compare to just using the render setting and when would you use one over the other?
What happens if I have the denoise setting turned on AND I also use the denoiser node?
