Hey everyone, i trying to understand how its possible made in maya or blender. So what i found is only camera mapping. But this technique awaible only for color (diffuse).
Projecting an image from the vector of an object (camera or otherwise) is absolutely not limited to diffuse. You can project anything you want (likely through an extra UV channel), and then pipe it as a bump effect. I have no idea about Maya, but in Blender at least it will then bake down just fine as tangent normal…
