Crest is a trusted water solution by many studios for its quality and performance. It has been implemented in several successful games & simulators and the subject of SIGGRAPH talks.

Crest 5 is now available. Crest 4 will still continue to be supported with bug fixes and minor improvements.

Workflow

Add water in minutes with three components (water surface, underwater and waves)
Sane and balanced defaults
Several example scenes covering many use cases
Detailed help boxes display validation errors direct in the inspector with fix buttons to guide setup
Online documentation with embedded videos

Features

Unity 6 ready including Render Graph & compability mode
State-of-the-art LOD system achieving class-leading performance
Innovative "equalizer" style wave authoring. Both FFT and Gerstner waves supported
Input system for modifying ocean data (like foam) using mesh, trail, line and particle renderers
Innovative "wave spline" technology to give detailed control over water simulation including rivers, lakes and shorelines
Simulated light transport including reflection, refraction, scattering, caustics approximation and shadowing
Underwater effect with partial submersion and meniscus
Query water displacement using GPU or CPU
Unity Server support suitable for authoritative servers (like MMOs)
Shifting Origin component provided for large/open worlds
Dynamic wave simulation ("ripple simulation") for dynamic object-water interaction including boat wakes
Shallow water - light scattering and wave attenuation
Foam simulated from waves and shorelines
Apply colour onto ocean surface similar to decals
Water volumes which can restrict rendering of both surface and underwater to a given geometry (eg sphere of water)
Flow to enable horizontal motion of water surface
Physics interface with buoyancy implementations and support for Dynamic Water Physics 2
Flexible time synchronisation to support networking and cutscene Timelines
Surface clipping to carve hulls/caves out of water surface
Planar reflections (except VR)
Deferred, Forward, Forward+, Perspective, Orthographic and Stereo (VR/XR) rendering supported
Shader Graph nodes for applying underwater to transparent objects
Gaia Pro VS integration
Much more…

To see some of these features in action, videos can be found on our YouTube channel. Furthermore, we have a Frequently Ask Questions section in our documentation.

Crest does not support OpenGL or WebGL and requires shader compilation target 4.5 or above. Crest 4 currently does not support WebGPU.

Asset Compatibility

We avoid non-standard techniques and are not aware of any major incompatibilities. Our users also use Dynamic Water Physics 2 (DWP2), Enviro, Cozy Weather, Buto, Expanse, Gaia, MicroSplat, MicroVerse, Nature Manufacture, Azure[Sky], Skybox Creator, Vegetation Studio, and many more…

Example Scenes

This asset comes with a few example scenes, including the 'Pirate Cove' demo scene shown in the videos. This scene was assembled by @patrickprosic, using terrain textures generously provided by RD-Textures.com.
