I'm trying to visualise a compact disc. See an example in the attachment.

I think it's something with spectral/anisotropy settings (?)
But I have no idea where to start.
I'm using the Octane plugin in C4D.

Does anyone knows how to start to visualise this?

thanks in advance, T

Pretty sure this material sucks but check this up.
If you take the time to place a specular material on top you can discard the 'b' part of the setup. I also used two gradients to add more variation to the bump (what you use to get the anisotropy) but you can be just fine with one. I'm also interest about how a guru would make this material.

Hi timpeters,
you can start by playing with Film width and Film Index in a glossy or specular material, here is a fast example with a sinewave in triangle mode, slightly reduced with a gradient node in the Film width pin: ciao beppe

Thanks for the replies!
I'll give it a try

Where is "texture pj" node for connect to "sine wave texture" node? But I've currently OR v2.26.1 standalone ONLY.

Thank you. but...
