Using sapphire plugins in Nuke such as s_sketch or s_autopaint it applies the effect as a 2d layer on top of your comp. Is it possible to track this effect onto elements in your comp? If there is any movement in the plate it becomes obvious the effect is just a layer sitting ontop and therefore the effect becomes noisy as the plates moves beneath it
Hmm, I’m not quite sure what I’m understanding. Could you make a short video to show what you mean? I love loom.com for this sort of thing.
