How to Apply Grungy Materials Using Sketch & Toon’s Spot Shader

April 24, 2015

In this tutorial, I’ll show you how to apply grungy materials onto your 3D models in Cinema 4D.  Sketch and Toon is such a deep module inside C4D and to go over this technique I’ll be introducing you to the S&T Spot Shader.  It works a bit like the Cel Shader, so if you’re not familiar with the Cel Shader check out my tutorial covering it.  Spot Shader is mainly used for creating halftone like effects onto your image, driven by the diffuse shading on your 3D objects but it’s very versatile as you’ll see in this tutorial.  If you have any questions, be sure to hit me in the comments below and I hope you enjoy!

  • Amazing tutorial.
    I am wondering if you could make a tutorial on how to model the whole thing (the pipe) with the animated water drop.


  • Ninja shading techniques, thanks EJ.

  • Any tutorial on how to model the pipe and water drop and animation please?

    Many thanks

  • Is it possible to remove the “Gap Color” altogether? (So that you are only getting the Spot Color on the material? I am trying to layer the grunge effect on top of another material, as if setting the effect to multiply, but only in the shadows.

    Many thanks!

  • Hey EJ, thanks for making this. I’m wondering how you got that nice grungy texture inside the shadow detail too – where you can see the shadow of the pipe falling onto the wall. Keep up the wonderful work man!
