Water Caustics

Water Caustics is an experimental resource pack that gives blocks animated textures using Continuity to simulate water caustics. These animations appear only on the top faces of blocks between Y-levels 55 and 62, and using Polytone, only applies to ocean biomes and rivers.

Changes

Affected Biomes
CTM can’t detect water or fluid states, so blocks can’t connect directly to water. Instead, caustics are determined by Y-level and biomes — specifically, only water 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. This is what makes Water Caustics an experimental resource pack.

• Ocean
• Cold Ocean
• Lukewarm Ocean
• Warm Ocean
• Frozen Ocean
• Deep Ocean
• Deep Cold ocean
• Deep Lukewarm ocean
• Deep Frozen ocean
• River

For creative uses, you can make 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.

Requirements

• Continuity
• Polytone

Recommended

Natrual Textures to give terrain blocks rotations, which rotate the water caustics with it, to look more natrual, as shown in screenshots.

Extra

An Emissive textures add-on is in the works.
