Can we get a denoise strenght setting ?

Is this possible ?

it's not really possible, since you plug sigmas directly into the SamplerCustom node.

what denoise 0.5, 20 steps is doing behind the scenes is generating 40 steps and splitting the sigmas for those 40 steps in the middle and then using the second half 20 steps for sampling.

a lot of scheduler nodes have a denoise setting though. for the ones that don't, you can can calculate the total steps using the formula steps/denoise and then use a SplitSigmas node to split the total steps into however many you actually want to run (use the second output).

example for 15 steps at 0.3 denoise:
