Post Process Video / buffer feedback effect ( smearing / updating render buffer using float map )

So maybe you can cook up a few render textures with a scene capture 2d, isolate the character via stancil, and make the postproces fade in the texture of the capture that matches the screen.

Oh my! I didn’t know about that node, I can’t wait to try it, I wonder if it can exist in the context of a post process material, and if not, if I can just plop a plane exactly to fit the camera view.

Best tutorials to look up for that are the reactive water ones. The wiki has a few and they aren’t very well explained.
However the process they have in the content examples loops and updates at least 3 different render targets over time to generate the geometry on the water plane.

This is by nature already very similar to what you need. Maybe you can adapt the whole concept.
and no, its not only a post process effect anymore…

This sounds really interesting, I’ll definitely check it out, I’m really curious how the reactive water system works, maybe key to doing some interesting feedback systems!
Thank you for your time!
