#AskGSG 2: How To Make A Bumpy Ruby Rock Texture

January 2, 2015


In this Ask GSG, “chmiewlski” asks how to make a Procedural ruby red texture using Sub-poly Displacement and HDRI Lighting like in this great piece by “TAVO.”

  • Awesome tutorial like always! Though, I have a suggestion, since you guys deactivated the share link in the video that redirects to toe video on Vimeo, it would be better if you embed the video in a bigger format so we could see the details, settings etc. Maybe rethink the layout of tutorial pages and make it look similar to the one on Vimeo. Video large on top, and comments + sidebar below.

  • Hey pretty new here. Is there an archive of your live streams?

  • Yet another great tutorial, thank you!

    Any tips on how to make the animation?

    • Yeh i’d like that too!

      • I think on the reference video they cloned the ruby on the rock.
        In my opinion for the animations they mostly used Plain Effectors with the scale set to -1 in the parameters, then you can animate the falloff on a short range like 30 frames.
        Same thing for the “growing” ruby. They broke it appart and then used plain effectors to animate the scale and the rotation of all the pieces.

        I can send you a C4D file if you like ๐Ÿ™‚
        Hope that helps !

  • Great tutorial,

    I’m looking forward to the next one…

    Oh and if you have time…
    It would really be helpful if you made a tutorial stating the differences between GGX,Beckman,Phong,etc

  • I got a lot closer to the original displacement through using two noise layers in the Displacement (both Luka noise) on top of each other. One layer with global scale 400%, low clip at 40%, high clip at 75%. This layer determines where the displacement happens and where there is a smooth surface. Then a second noise layer (set to Multiply instead of Normal) with global scale set to 70%.

    • Thanks for the tip! Sounds good, will try!

    • Thanks but i don’t understand how you get 2 layers on the displacement. Where can i add layers in displacement tab ?

      • Hey Emmanuel, to add a layer what you want to do is go to Displacement>Texture>Layer. This is going to leave you with the option to add another texture. Click on the noise texture, and you should see some options. Image, Shader, Effect, Remove, etc. Click on Shader, and go to Noise. Boom, two customizable displacement layers ๐Ÿ™‚ Hope this helped!

  • Great tut Nick, awesome stuff..keep up the good work ๐Ÿ˜‰

  • That’s what always amazed me about C4D, how you can very easily create these awesome displacemants and bumps!
    Awesome tutorial Nick!

  • You could maybe do a vertex map as layer mask in displacement channel to refine where displacement should happen.

  • Hi,
    Thanks for all the tutorials over the years, they’ve helped me no end.
    Just a thought for the shape of the crystals… Capsule with 1 height segment, 1 Cap segment and 4 rotation segments.
    Looking forward (as always) to the next tut.

  • I’ve been messing around with these types of things since I asked the question, you can get pretty close using noise like Jeroen said. If you want extra control of where the displacement/bump takes place you can always use a gradient or even another noise as a layer mask.

    Another option rather than using displacement is to use the displacer object but this can get polygon heavy if you don’t watch out.

    here is an example image using bump instead of displacement


    thanks for taking the time to answer the question Nick ๐Ÿ™‚

    • Nice render man ๐Ÿ™‚
      Thanks Nick for another awesome tutorial about my work


    • Looks amazing!

      How did you make it break?


      • Than Menano,

        i used this plugin from Nitro4D http://nitro4d.com/blog/freebie/thrausi/

        there are lots of tutorials on how to use this but this is the basics:

        after the object was cut up into the amount of pieces i want and a dynamics tag was added (all done by thrausi) I then animated a clone with a dynamics tag applied hitting into the object. (make sure you have gravity set to 0 in the dynamics setting if you don’t want the pieces to fall down)

        I turned off that objects visibility and let the simulation play out and then found a frame I liked the look of.

        I hope that helps… ๐Ÿ™‚

  • Thank you for this awesome tutorial, Nick.
    Also congrats to you TAVO – great work!

    This is my rendering result of this tutorial. Iยดd love to animate… ๐Ÿ™‚


  • Hi Chris etc.

    Would any of you be willing/prepared/foolish enough to attempt a tutorial on how to “do” origami in C4D? Obviously, one can mimic a finished, folded object just by eye, but I’m trying to go deeper than that and actually animate a finished piece from a single plane (with thickness, that’s the tricky bit), just like one would in the real world with a sheet of paper. I think back to your tut on building the card box. It’s the intricate attention to detail, paper thickness, fold integrity etc that would make the difference.

    There are a million step-by-step origami instructions out there and I just think it would make the coolest tutorial… (e.g. https://s-media-cache-ak0.pinimg.com/originals/d0/72/a4/d072a41b0b0961b02d1cc9b22144c010.jpg)

    Many thanks

      Further thoughts on the origami request:

      I know most of your tuts lean more towards the lighting, textruring and animation side, rather than modeling. Most of my work, likewise. But would origami be best handled by rigging, or morphs? Would it be single plane? How to make folds that truly represent the gradual increase in thickness of the “paper” (sometimes four folds stacked upon each other). How to deal with already-folded edges that then get folded back on themselves…? I think there’s a lot there to make a cool tutorial, and cracking the process would allow users to take things to as complex a level as they like. Maybe a challenge in the making?

    • Hey, MoStyle did a great tutorial on this theme but Iยดm not sure whether this is what you mean:

      Also maybe the new cinema4d packaging functions might help you a bit:

    Oh gawd, I love you Nick!

    Great stuff as always!

  • Hey man great tutorial. I started getting lost with the material once you started playing with the reflectance option. I only have C4D 14 studio… Am I a lost cause for the rest of this tutorial or are there similar options for me?

  • I downloaded that sIBL Loader plugin and was wondering where you got your presets.. Is there any blog or video about this plugin, or anywhere I can purchase the sets you guys use? Thanks!

    • In case you never figured it out or somebody else is asking this same question. The presets are on the same site under their sIBL archive. Just download them and unzip them into a folder, then search for the folder from the loader.
