12 static construction props with 24 prefabs, four scenes, optional collider profiles and a bundled Blender/GLB source archive.Tested in Unity 6000.3.25f1 with the Built-in Render Pipeline. The retained optional URP material set and HDRP are not certified by this update. Generated UV2 is verified; an artifact-free lightmap bake is not claimed. Static props with optional primitive colliders; no Asset Store dependencies.Populate construction scenes with 12 static props: Traffic Cone, Safety Barrier, Hard Hat, Wheelbarrow, Shovel, Cement Bag, Toolbox, Road Sign, Portable Work Light, Brick Stack, Rebar Bundle and Caution Sign. Includes 24 prefabs (12 default plus 12 optional primitive-collider variants), four scenes and Built-In/URP material sets. A separate source ZIP contains the Blender scene, source scripts, and 12 GLB plus 12 FBX exports; these source files are bundled inside the ZIP. The 12 source meshes total 41,568 triangles. Validated in Unity 6000.3.25f1 with Built-In only; URP materials are included but were not newly validated. Optional colliders are static approximations, and the Wheelbarrow tray AABB fills the basin. UV2 data is included for static-lighting workflows, but no baked-lightmap result is claimed. No animation or runtime behavior is included.• 12 unique static props; 24 prefabs (12 defaults + 12 optional primitive-collider profiles); 12 FBX model assets; 4 scenes.• 41,568 source triangles total; 61 PNG texture assets.• Embedded Source/ConstructionSiteEssentials_source.zip contains ConstructionSiteEssentials.blend, 12 GLB exports, 12 FBX exports and reconstruction/export scripts.• Built-In and URP material sets; Unity 6000.3.25f1 validation was Built-In only. No HDRP materials.• Optional colliders are static approximations; Wheelbarrow tray AABB fills its basin. Generated UV2 data does not establish baked-lightmap readiness. No runtime behavior or animation.AI-assisted procedural authoring was used for Blender/Python geometry and export tooling, Unity scaffolding, validation scripts and documentation. The meshes and material maps were generated procedurally from authored code; no generated-image textures or third-party stock models are included. Marketing images combine renders of the included models with an AI-generated empty studio background from ChatGPT > Agent Assets; this background is presentation-only.
