Unity Asset Store – KWS Water System (HDRP Rendering) v1.2.0

Water System is a module based component allowing you to simulate such water surfaces as an ocean/sea/river/lakes/pool/etc. Water System targeted at PC/console platforms and HDRP rendering.

This version is only compatible with HDRP rendering and is not compatible with Standard built-in/ URP/ Mobiles / VR / WebGL

Required compute shaders support and HDRP 10+

Before updating, be sure to delete the old version!

Water rendering uses physical approximation for lighting/wave simulation and is based on such physical parameters as wind power, turbidity, transparency, dispersion, etc. Therefore, the rendering of water should look correctly in any scene, for example, during the day, at night, at sunset, or in the cave.

Features:

GPU waves simulation with multiple cascades (to avoid tiling)
Physical approximation of lighting (volumetric lights and shadows, absorption, scattering, caustic)
Physical approximation of reflections using fast screen space projected reflections, camera planar reflections, baked and realtime reflection probes.
Physical approximation of refraction in screen space with dispersion (using water IOR)
Physical approximation of caustic relative to water depth and waves (with dispersion).
Underwater effect (with partial submersion)
Shoreline waves rendering with foam particles
Flow rendering using flowmaps (integrated flowmap painter)
Fluid simulation for static objects (rivers)
Buoyancy
Dynamic waves
Rain effect
Finite/Infinite mesh support (ocean/pool)
Depth (stencil) masking (to avoid water rendering in boats, etc)
Tesselation
Depth buffer writing (for correct posteffects like 'depth of fields')
Offscreen water rendering with scalable resolution (for example water can be rendered with resolution: 1080p, when scene rendered in 4k)
Video/text description of each setting in the editor.
