I'd like to figure out holo shaders too but i have a couple questions to get me started.

Q1 = Would you just start with the hologram.shader_template?

Q2 = What kind of bitmaps would you use? A bump type? Or could you use one from mudbox?

I'm guessing my answers will be something like - "You dont know what your talking about " - but i gotta start somewhere, i don't mind criticism.

Maybe the answers will help beele too.
