Realistic construction site and roadworks kit: 22 high-detail heavy machines, concrete frame with scaffold and formwork, site props, road and traffic modules, with a 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.Build a believable construction site and a road under repair from parts based on real site practice. 22 heavy machines in working poses, each with a 4K PBR atlas and LOD1: a new 20 t crawler excavator (track shoes and links, rollers, banana boom, hydraulic cylinders and hoses, bucket with teeth, cab interior), an articulated wheel loader (OTR tyres with chevron lugs, Z-bar linkage), an 8x4 transit concrete mixer, crawler dozer, motor grader, skid steer loader, mini excavator, tipper truck (body raised), cold milling machine, asphalt paver, tandem roller, hammerhead tower crane, all-terrain mobile crane, knuckle boom crane truck, telehandler, articulating boom lift, scissor lift, rotary piling rig, truck-mounted concrete boom pump, tracked jaw crusher, towable generator and a site office container.Building site modules on a 6 m grid with 3.5 m storeys: concrete column, beam, slab, slab with rebar mat, core wall, stair flight and edge protection; column and slab-table formwork; scaffold base, lift and ladder bays with braces, ties and debris netting; mesh fence, hoarding with gate, site cabin, toilets, wheel wash, light tower, skips and a materials yard (bricks, cement, rebar, timber, pipes, sand).Roadworks modules: new and cold-milled asphalt tiles 8 x 8 m, precast kerb, manhole, steel road plate, road markings, concrete safety barrier, red and white water-filled barriers, pedestrian barrier, traffic cones, delineator posts and a temporary warning sign. Ground tiles: dirt, site mud with tyre tracks, gravel, concrete, pit floor, excavation edge and pit wall.Unity package: 79 prefabs with LODGroups and colliders, Standard-shader materials with lossless PNG textures, a demo scene with a fenced 4-storey concrete frame site (scaffold, formwork, concrete pour, tower crane), site compound, excavation pit, crushing yard and a 2-lane road with a closed lane and the milling, paving and rolling train (1,198 placed prefabs), plus 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: 79 static meshes as prefabs. Polygon count: about 1,499,000 triangles in total, one of each mesh (per-mesh counts in Documentation/module_list.csv); large machines 10,000-151,000, site modules 12-2,300. LOD information: LOD1 (about 45-55% fewer triangles) on the 22 machines and every mesh above 2,500 triangles, set up as LODGroups. Collision: convex MeshColliders on every prefab except road markings (hand-placed hulls on the large machines). Number of textures: about 166 PNG files (BaseColor, Normal, metallic/occlusion/smoothness). Texture dimensions: 4096 x 4096 (machine atlases), 2048 x 2048 (tileable sets). Types of materials and texture maps: Standard-shader PBR materials. UV mapping: Yes, real-world texel density on the site modules (lightmap UVs generated on import). Rigging: No. Animation count: 0. Real-world scale in metres.
