Editable stylized URP water with shoreline foam, animated caustics and Rigidbody buoyancy, plus a lagoon demo with three presets and interactive controls.Tested: Unity 6000.3.25f1, URP 17.3.0, Windows/D3D11. Forward renderer; Linear colour; Depth Texture; Copy Depth After Opaques; Depth Priming Disabled. Requires URP and Unity UI via Package Manager. Horizontal XZ water, above-water perspective views. Caustics need the receiver shader. No Built-in, HDRP, Deferred, XR or mobile support claim. Setup and limits are documented.Create a stylized lagoon, pond or shoreline with editable water shaders and reusable buoyancy components.The package includes a transparent water surface with shallow/deep colours and animated waves, depth-based shoreline foam, a caustics receiver shader and point-based Rigidbody buoyancy. Tune the materials and wave profiles to fit your scene.Included showcaseA saved Lagoon Lab demonstration scene with Lagoon, Alpine and Sunset water presets.Reusable water surface, navigation buoy and timber float prefabs.Controls for presets, foam, caustics, wave strength, pause, reset, camera orbit and zoom.Editable C#, ShaderLab/HLSL, original foam and caustics mask PNGs, demo geometry and setup documentation.ScopeFor above-water views of horizontal, world-aligned water in URP Forward. Caustics require the included receiver material, and shoreline foam requires opaque depth. Buoyancy is a point-force gameplay approximation. Reflection, refraction, underwater rendering, wakes, collision ripples, a boat controller and networking are not included.Unity 6000.3.25f1; Universal Render Pipeline 17.3.0; Forward renderer; Linear colour space.Two editable ShaderLab shaders: Transparent Surface and Caustics Receiver; shared HLSL wave functions and one compute probe.Three runtime components: WaterSurface, BuoyantBody and CausticsReceiver. Sample UI and orbit controls are included.Two original RGBA PNG masks, 1254 x 1254 pixels each; configured as linear data with alpha, mipmaps and Mirror wrapping. The supplied nearest-power-of-two import setting yields 1024 x 1024 runtime textures.One saved demonstration scene, three water appearance presets and three reusable prefabs.Requirements: URP and Unity UI via Package Manager. Enable Depth Texture and use Copy Depth After Opaques; setup is documented and project settings are not replaced during import.Horizontal, axis-aligned world-XZ water only. No Built-in, HDRP, Deferred, XR, mobile or non-Windows compatibility claim.Caustics are a stylized receiver-material overlay with manually controlled intensity and light-direction/shadow modulation; arbitrary existing materials are not modified automatically.ChatGPT image generation in the publisher’s Agent Assets project created the original foam and caustics PNG masks. Codex and AI agents assisted with editable C#/ShaderLab/HLSL implementation, procedural demo geometry, Unity scene integration, documentation and quality review. The included masks retain their recorded provenance and original image bytes. Marketing images are captures of the actual Unity demonstration scene.
