How to Create an Iridescent Material in Cinema 4D

February 11, 2016

In this tutorial I’m going to show you how to create an iridescent texture in Cinema 4D.  I’ll start by building up a scene to apply materials to.  I’ll then go over the Spectral Shader that applies prismatic color reflexes, or pearl like effects to your specular channel.  We’ll cover all the options inside the Spectral Shader as well as how lights and camera view can affect how the effect is applied to your object.  Finally I’ll give you some hints as to how you can create a soapy bubble type of effect using the Spectral Shader.  Have fun and experiment!

If you have any questions be sure to post it in the comments section and if you create any cool iridescent textures, be sure to share it with me!  Thanks for watching!

  • Cool stuff. I didn’t know about the mograph selector before. Keep the tuts coming 😉

  • Well done Ej! All your tutorials are interestingly cool.

  • Beautiful.
    Such a simple idea.
    One of those gems hidden in the deep recesses of Cinema C4D.
    Thanks for exposing hidden treasures.

    Such a breath of features in one overlooked shader.

  • I notice that when you turn on global illumination this effect just disappears. could you tell me why? Or how to get this effect while using my ultra realistic GI renders?

  • Hi guys !
    Thank you for all yours tutos !

    I have a question, how can you make the same shader but with Arnold Render ?
    I can’t find any good solution for cinema4d.
    Maya have some information/forum/solution about this probleme, but i can’t find anything for Cinema4d.

    Have a good day !

    • This would be fairly easy to achieve using facing ratio nodes feeding a ramp. Or you could try using the new thin film shader as well. Thanks for the comment!
