Underwater Caustics Part 2 - Advanced Materials

Uploaded February 2024 | Updated September 2026, 2 weeks ago

In this shader tutorial for Unreal and Unity, we add some polish to the caustics shader we created last week. We make the decal fade out at the edges, and I show how to calculate face normals for blending the triplanar projection - to fix the pixel normal artifacts.

Here's last week's tutorial on creating the caustics shader:

$Water Depth Shader - Advanced Materials - Episode 39 In this shader tutorial for Unreal and Unity, I show how to add depth to our water shader. We use the depth mask to make the water more opaque as it gets deeper.
