how to cleanly add transparent image planes, or overlay material, ontop of another mesh in 2.9 To add extra decal to my meshes that will only show up when I need them to, how do I add planes with an image to another mesh. Simple snap to face doesn't curve it and sticks out and shrink wrap deforms it way too much, also keeps trying to stretch it and attack to things not close to it. I know I can do a shape key like thing, tho I might have to, but then ill have tones of messy shape keys. So does anyone know of a way to smoothly, without deform, an image plane over a non-flat mesh, i.e. parts of a human or clothing. Also, this is for a toon/anime style animation, if that helps.
I'm using blender 2.9 and the eevee render engine.
sorry i should have given an example of what im going for. this is just one of the effects im hoping for.
I also think that the better way to achieve your goal is the use of UV, materials, decals over the same mesh,  but if you really want to use a different mesh you can duplicate the object, add a solidify modifier with an appropriate factor, apply it and  delete the unuseful faces.
