Before updating, remove the old version and the folder "streaming assets/WaterSystemData"

Sometimes unity tries to use the cache of old shaders instead of new ones. if you will have some shaders errors, try to remove the "Library/ShaderCache" folder from the project and restart unity.

1.4.04

-added urp15+ support

-fixed finite mesh performance issue

-fixed some issues with native/third party fog

-fixed ps5 support

-fixed buoyancy issue in build

-fixed caustic rendering with multiple water bodies

-fixed some macos issues

1.4.03

-fixed vulcan build issue

-fixed single pass/multipass VR rendering

-fixed underwater far clip issue

-fixed mesh flickering

-fixed underwater horizont flickering

1.4.0b2 (for unity 2021.3x+ and URP 12+)

- Added instanced quadtree mesh rendering for Infinite/Finite mesh. (faster than tessellation with the same mesh detailing))

- Added automatic mesh quality relative to wind speed

- Added VR support

- Added multiple reflection stack (cubemap + planar layers + SSR)

For example, you can use planar layers for important objects (characters, mountains, trees, etc) and SSR reflection for other scene. This helps to avoid SSR artifacts.

- Improved SSR reflection (added temporal reprojection for hole filling and border stretching)

- Added new shoreline rendering for water surface waves + foam particles

Several times faster and takes up ~5 times less VRAM.

- Added infinite shoreline rendering with stacking feature (without artifacts of waves intersection).

- Added new shoreline API, you can change waves at runtime. (WaterInstance.Settings.ShorelineWavesScriptableData, see the readme for details)

- Added wireframe mode for rivers

- Added "enable mesh rendering" feature. It allows you to render only foam particles/caustic without water mesh.

- Added profiles for common water settings and water features (you can separately save shoreline/flowmap/fluids/spline profiles)

- Added infinite ocean mesh stretching

- Added beta version of the foam rendering (using depth buffer)

- Added simple buoyancy reaction for rivers

- Improved/changed editor GUI

- Added underwater queue (before/after transparent). Right now you can use transparent shaders, but without underwater fog.

- CG Allocation optimisations

- Optimized keyword variants (x10 times)

- Added new API

-WaterInstance.ForceUpdateWaterSettings //You must invoke this method every time you change any water parameter.

-WaterInstance.IsWaterRenderingActive //You can manually control the rendering of water (software occlusion culling)

-WaterInstance.WorldSpaceBounds //world space bounds of the current quadtree mesh/custom mesh/river (size relative to wind)

-WaterInstance.IsCameraUnderwater //must be obvious 🙂

-WaterInstance.IsPositionUnderWater/WaterInstance.IsSphereUnderWater //Check if the current world space position/sphere is under water. For example, you can detect if your character enters the water to like triggering a swimming state.

-WaterSystem.GetWaterSurfaceData // Get world space water position/normal at point. Used for water physics. It check all instances, instead of the old method.
