Realistic mountain hydropower dam and the valley around it: gated spillway, powerhouse, 220 kV switchyard, trees, scanned rocks, terrain tiles, river and lake water, full demo level.Built and tested with the Built-in Render Pipeline (Standard shader) in Unity 6000.6. URP users can convert the materials with Window > Rendering > Render Pipeline Converter. HDRP is not tested.A realistic mountain hydropower scheme and the whole valley around it, ready for games and visualisation. Everything is real-world scale and built from generic designs within typical published dimensions.Nature, usable on its own: 3 conifers (6, 14, 22 m) and 3 broadleaf trees (9, 10, 15 m) made of cut-out branch and leaf cards on atlases composed from CC0 leaf and twig scans, 2 shrubs, fern, green and dry grass clumps and patches, 6 photo-scanned rocks (cliff faces, boulder, moss rocks, mountainside, stump). Terrain tiles that snap on a 50 m grid (river bank, gorge sides to +45 m and +60 m, flood plain, riverbed, meadow), an 80 m hill, a 120 m ridge and a 1200 m forested backdrop range, each with a baked splat texture. River and lake water surfaces.Dam and power: gravity dam blocks for 60 / 40 / 20 m height with stepped downstream face, crest road, parapets and lamp posts; 16 m spillway bay with ogee crest, chute, flip bucket, piers and hoist house; a 12 x 14 m radial gate as a separate prefab pivoted on its trunnion (open it in game); intake with trash racks, penstock modules, 3-unit powerhouse, tailrace, 250 MVA transformer, 220 kV switchyard bay, lattice transmission tower with a 300 m span, crest gantry crane.Construction: rockfill cofferdam, diversion tunnel portal, concrete batching plant with silos, plus tower crane, mobile crane, mixer trucks, haul truck, excavator, wheel loader, site office and light tower.Unity package: 60 prefabs with LODGroups and colliders, Standard-shader materials with lossless PNG textures, a demo scene with about 5,950 placed objects (gorge, dam, reservoir, river valley, forests, switchyard, construction yard, mountain ranges) and a catalogue scene. Tested in Unity 6000.6 with the Built-in Render Pipeline. Static meshes only: no rigging, animation or scripts. Original design, no brands.Category: 3D/Environments/Industrial. Number of meshes: 60 static meshes as prefabs. Polygon count: about 480,000 triangles in total, one of each mesh (per-mesh counts in Documentation/module_list.csv); trees 1,500-6,200, terrain tiles 3,000-14,400, dam blocks 700-2,500, reused machines up to 94,000. LOD information: LOD1 on every mesh above 2,500 triangles (authored for the vegetation), set up as LODGroups. Collision: convex MeshColliders on props, machines, rocks and tree trunks; non-convex MeshColliders on terrain tiles and dam bodies. Number of textures: about 170 PNG files (BaseColor or BaseColor+Alpha, Normal, metallic/occlusion/smoothness). Texture dimensions: 2048 x 2048 (unique baked splat per terrain tile, foliage atlases, tileable sets), 4096 x 4096 atlases on reused machines. Types of materials and texture maps: Standard-shader PBR materials, cutout foliage, transparent water. UV mapping: Yes (lightmap UVs generated on import). Rigging: No. Animation count: 0. Real-world scale in metres.
