Ocean & Shore: Coral Shallows - Reef environment

An underwater reef kit filled with chunky corals, crawling critters, and flocking fish for tropical adventure games. 200+ ready-to-use prefabs, plus ready-made moving versions of the critters and fish, with procedural sway and crawling behaviors.

Coral Shallows includes some utilities to get your ocean reef scenes going fast. Kelp, seagrass, seaweed and anemones sway with the included Shader Graph shader. Fish swim using the same shader and school with a simple flocking script, and snails and other critters crawl along surfaces with the Surface Crawler script.

Every pack in the Ocean & Shore series draws its colors from the same palette texture, so packs mix seamlessly and can be recolored together or one at a time.
