It is best to get a matching set of inversion noise that cannot be used by others, Or give an example of inverting noise with a custom node #17

Custom nodes can invert noise, but the sampler cannot remove the inversion noise. The purpose of adding inverse noise is to mix some noise of the original image together and then sample them together to achieve the purpose of removing the original noise. However, unsampler and custom sampler It bothered me for a long time, it can't be as simple as a1111. Please give an example of how a custom node can invert noise and use sampling to eliminate original noise. I think many people are troubled by this problem like me.

agree

I have a hard time understanding this as well. Noise inversion option would be nice for upscaling.
