i wanted to see it if was possible to clone from a 2D image and paint directly on a 3D model
normally this isn't possible - you can clone from 2D to 2D and 3D to 3D but you cannot clone from one editor (image editor) to another (3D viewport)
the solution is to cheat
parent a plane to the camera with your 2D image, and make it become part of the mesh you are painting on with geometry nodes. this lets you sample from it while painting
it could be sorta useful for decal sheets, though at that point you're probably better off with a standalone texturing program. this workflow is excellent for shitposts however
