Hi, (before i open up with everything i got to say about this my question is to anyone that is able to help me with exactly how to make cd shader in arnold and I would be very grateful to this person!)
lately i was greatly interested in making cd/dvd shader in cinema4d with arnold(which i am new to) that would look realistic. I dont know if there is a certain way of approaching this but I wasnt satisfied with both ways i tried to make it. Someone already told me that it should be done using thin film interference and anisotropic shading but He didnt add more about this and I have no idea how to add thin film to anisotropic reflections.
1. First approach I tried was to make thin film interference with anisotropic shading but that look very not realistic it just look bad and I wasnt sure which direction i should go with that. That might be the right way to it but I have no idea how to deal with this. It wasnt glossy couse i needed to turn on roughness for anisotropy to be visible.2. Second approach was done with stacked nodes that were supposed to give an impression of a cd by imitating how these reflections would look like. Pure experimenting and also this outcome looked bad 😞 . Atleast it was glossy and had some colorful rays. Also light may be important here but i always use one point light and two quad lights while trying this.
I have noticed that the last standard surface node that was added to mix shader node here actually gave nice looking colorful reflections. To make that i added ramp float to ramp rbga with a rainbow colors and then added ramp float to specular rotation to change the shape of relfections. Maybe that is the right way... this is how this one node alone looks :Thank You to anyone that helps me Im trying to make 3d graphfic for my friends birthday as a present and im counting days
I would really appreciate your knowledge on this.

I've been working on a scene that uses a similar shading technique to yours. I'll do a video tutorial about it at some point.
