List of render settings you can change during rendering which wont restart iterations?

Only a Noob

hey guys,

I cant seem to find a unified list online. Also, specifically the firefly filter. Right now I have a complex scene rendering which has nearly reached 20k iterations in 6 hrs, currently the firefly filter is OFF, if I turn it on what will happen?

The render will restart. In my experience, which i will admit is not vast, the only setting that will not restart the render is increasing the number of iterations.

As far as I know the only setting you can adjust without restarting the render is tone-mapping. Also perhaps filtering effects like Bloom or Post Denoiser but I'm not sure about those, don't use them.
