Water Caustics Surface Shader - Posted on: 2/6/2020 [Uncategorized]

I recently learned that projectors aren't supported in Unity's new render pipelines, so I've been trying to convert my projector-based water caustics shader into a surface shader...

The disadvantage of using a surface shader versus a projector, is that the image is not projected onto all surfaces. So, naturally, the surface shader effect will only work on objects using the same shader. For example, this will not work with Unity's Terrain shader, or transparent objects, etc.

With that said, the results look really good, and the methods used in the shader could probably be applied to other shaders, so I'm happy to share it when it's done.
