Projectors that can project bumpmapping?

Unity Engine

I posted this in ShaderLab, but I don’t think anyone noticed, so…

Is it possible to create a shader for a projector that will create a bumpmap effect on whatever it is projecting on to? If anyone reading this has read any of my recent threads about transparency and footprints, I can’t use projectors to do them because 1)I’m using a bumpmap effect for the footprints and 2)I don’t think projectors can fade in and out with transparency (if I’m wrong on either of these suppositions, PLEASE correct me).

In actuallity, a projector would be ideal for this since I wouldn’t then have to figure out how to match the footprint tile texture to the terrain texture. It would be perfect if I could just point the projected bumpmap onto the terrain where I need it.

Is it possible?

(and, as I think about the possible applications of such a shader, craters and any other such depressions created by impacts could also be done the same way)

Hey, I saw your post but I haven’t come up with any good ideas yet. Still thinking. I’ll post in Shaderlab when I come up with something (or an explanation of why I can’t).

  1. thats possible and controlled by the textures. You can project any shape on the texture you want actually.

Ok. That’s what I was hoping on the transparency issue.
