Hi, I'm trying to make a hologram shader in mental ray as credit cards, anyone have any tips on how to do something like that?

This is an example in render man, but I would like to do in mental ray:

Thanks!

that render man shader wont give you this effect, that uses relief mapping to fake depth on a 2d surface.

I would just break the effect down, these holograms are usually made up of 2-3 images, and change depending on viewing angle. So you could render out the bird from a couple angles, and use something like the sampler info node to blend between the image depending on the camera angle.

Getting the shifting spectral colors right might be tricky though
