How to Add Caustics In Cinema 4D 49 Comments


In this video, I will show you how to set up some simple caustics on a scene. Caustics allows light to bounce off of reflective objects and go though refractive objects to produce realistic light patterns. Caustics can take a long time to calculate, but in product shots, it can really help with making the scene more realistic.

  2. Nice, although it might have been a better example to use glass, since that is often where caustics are needed. Nevertheless, great tutorial as always. Keep up the god work Nick!

  4. LOVE your new site, brother! Practically every bit of it is embracing, just not that weird grey 45º drop-shadow on the text in the header items. That’s all, haha! :)

    Keep it up, you rock!

  5. Hey Nick, I’m getting some strange display problems with the site. The text in the description for the tutorial runs into the column on the far right. Looks fine when I click on the link and go to the post though.

    Hey there, Can you supply us with maybe some texture files? If not I understand why. My metalic structure isnt anywhere near as good as yours…. Id just like to see if spruced up.

    Very Pretty! I like how with caustics there is some light that bounces off of the surface to fill in some of the shadow areas.

      Nice tip FETHI. It definitely adds that little x-factor to the scene.

    Hi,

    Can caustics be used with the GSG Light Kit Pro???

    As I understand it, all lights are disabled in the scene and luminance is used.

    Thanks

  16. Im not sure why, but the floor I’m using isn’t picking up the caustics.

    I’m trying to animate some little crystals growing out of an arm rail in live-action footage.

    so, my floor is a cylinder (sized to match the real rail), and I have it textured with the background image set to “frontal” and a compositing tag to make it invisible against the background to catch the shadows and caustics.

    the shadows are being cast onto it correctly.
    but the caustics aren’t.

    I have everything checked from this tutorial and to double check, I set the caustics to render as a separate multi-pass.
    In the caustics multi-pass channel of a single-frame render, they show up, but in the overall composite render there’s nothing there, which makes me think it’s the floor surface.

    Any suggestions?

    Hi Nick,

    Have you experimented with caustics using just GI and a luminance material?

    I’m working on a neon tube light which has the illumination on the material cranked up to generate more light and I wanted to add a bit more to it by adding caustics but not getting anywhere with the neon tube being the only light source.

    Cheers,
    Stephen

    Hey Nick! Thanks for the tut and all of the help you have provided me! One thing I do know about the Caustic effects, is the Energy percentage controls the overall brightness and not only can the effect be controlled in the light(s) and render settings, but the material settings. In the material settings, if you go to Illumination, you will see it there. You can also control the radius of the dots in the same location. Cheers!

    PS: You prolly know all of this already.
