CTM can’t detect water or fluid states, so blocks can’t connect directly to water. Instead, the texture is determined by Y-level and biomes. If any other biomes were added to the list, caustics could appear on blocks that aren’t actually underwater, such as beaches or any land biomes bordering the ocean.

For creative uses, a workaround for this, is making caustics appear next to land biomes that border oceans and rivers, by using Axiom (?) or WorldEdit (?) to change the water’s biome to one of the ocean biomes.

For the best results, use Natural Textures to give blocks rotations, which rotate the water caustics with it, and removes the grid-like pattern, as shown in screenshots.
