URP.Fill ponds, rivers and lakes with living underwater vegetation. Every plant sways with the water current in the shader, with no bones and no Animator, so thousands of plants stay cheap. One component sets the direction, strength and speed of the current and of the wind for the whole scene.Plants (10)Canadian waterweed (Elodea canadensis)Hornwort (Ceratophyllum demersum)Eurasian watermilfoil (Myriophyllum spicatum)Shining pondweed (Potamogeton lucens)Sago pondweed (Stuckenia pectinata)River water-crowfoot (Ranunculus fluitans)Tape grass (Vallisneria spiralis)White water lily (Nymphaea alba) - floating leaves stay on the surfaceYellow water lily (Nuphar lutea) - floating leaves stay on the surfaceCommon cattail (Typha latifolia) - stands above the water and sways in the windUnderwater props (14)Mossy log, sunken snag, tree stump with roots4 waterlogged branches, 3 river bouldersRusty anchor, rusty barrel, old wooden rowboat, deer skullLakebed Terrain Layers (4)Silt, river sand, pebbles, algae bedSeamless 2K textures with normal and mask map, height-based blendingFeaturesSway shader driven by a vertex color mask: bending from the root, leaf flutter, random phase per partWater current and wind in one component (FWP_WaterCurrent): direction, strength, speedPer-plant sway amount, speed and translucency in the materialPaint the plants on your terrain with the Paint Trees tool - LODs and sway are keptFull PBR on every model: BaseColor, Normal and Mask Map4 LODs with cross-fade on every model, Box Collider on every propReal-world scale, pivots at the baseDemo scene: one lake with all 10 plants and all 4 bottom layers, water surface, underwater fog and color grading, free-fly camera and a labeled showcase row of all 24 modelsHow to testOpen Scenes/FreshwaterPlants_Demo and press PlayHold Right Mouse to look, WASD to move, Q/E down/up, Shift faster - dive under the waterSelect FWP_WaterCurrent and change the current or wind - all plants react at onceTerrain > Paint Trees > add a prefab from Prefabs/Plants and paint it on your own terrainUnity 2022.3 LTS or newer (Unity 6 supported), Universal Render Pipeline 14+Built-in and HDRP are not supported (custom URP shader)24 prefabs (10 plants, 14 props), 4 LODs each (100 / 50 / 25 / 12.5 %)LOD0: 2,878 - 20,577 triangles per model, 354,367 triangles in total22 materials, 69 textures, 4 Terrain LayersBaseColor and Normal: 2048 for plants, 4096 for props; Mask Map at half size (1024 plants, 2048 props); lakebed layers 2048Normal maps OpenGL; Mask Map: R metallic, G AO, B detail/height, A smoothnessCustom URP shader "SGTrade/FWP Plant Sway": two-sided, translucency, GPU instancing, shadows, LOD cross-fade3 C# scripts (current and wind, underwater camera, fly camera), no external dependencies1 demo scene, documentation in Documentation/README.txt
