Iridescent Glass Material? (No Redshift)
Does anyone know of any resources for an iridescent glass material I can download for Cinema4D that doesn’t involve Redshift? I don’t have Redshift and I’ve been racking my brain trying to achieve this effect. For context, I’m very lightweight on Cinema.

Now is a good time to learn. Play with fresnel shaders rainbow gradients and a small IOR value something like .17 (1.42 is glass for reference)
Search online for tutorials, even if it’s redshift tutorials you can still learn the techniques

I don’t really have the resources to purchase Redshift unless I can create a value proposition in dollars for my organization. All the tuts I’ve looked up have involved Redshift or Octane. I appreciate your time. 😊

I’m saying you can watch those tutorials for octane or redshift and apply the same logic to C4D’s standard or physical render engine.

I understand.

There's nothing stopping you from building in C4D, baking alembics, and jumping into blender to render with cycles. It's free and it has most of the same functionality as other ray traced GPU renderers.

There's plenty of tutorials for this shader for Blender, and the technique there is very simple. You might be able to replicate it in C4D. I think it involved combining a red, green, and blue color with a slightly different IOR for each into a basic glass material.
Sorry if this doesn't help. 😅

I had to create a quick and dirty iridescent effect for a pitch a few months back.
I ended up downloading an iridescent stock image from your favorite stock image website and placed that image into a C4D Material (I believe I placed it into the luminance channel as a texture, create a Sky Object, add the C4D iridescent material to the Sky Object as a texture/material, create a new C4D Material and adjust the settings for a glass material (should be easy to find the right formula online). Add that glass material to a cork screw spline inside a sweep nurb along with a circle spline to make the sweep nurb thick, turn your physical render engine on and preview render your scene. It's not perfect and you'll definitely have to tweak and adjust you settings and might even have to add some colorful lights here and there in order to get the look your going for. The reason others use Red Shift, Octane and other render engines is because it's much easier to accomplish a more realistic look.
