Water Caustics Generator

Water Caustics Generator

Get your goggles out!

Caustics are pretty expensive to render in 3D, so the best way is to fake them. With this substance file you can create a seamles gobo texture of looping water caustics to use in your scenes. With a gobo technique you place a texture in front of a light source. You can just use 1 frame if you need it for a still image. I've included the Blender scene file so you can see how I've used it in my scene. I had to prepare a sequence of 2K of the substance results which are included in the zip file. 

The substance shader is now working with the timeline in the substance player, freely available here https://helpx.adobe.com/substance-3d-player/home.html. This gives you the ability to export sequences for use in your pipeline. I also did an overhaul of the parameters you can use.
