Voronezh Koltsovskaya Tower

One independent architectural asset; day/night variants share geometry. 135,812 triangles; 11 materials. Working Blender mesh: 60,116 quads and 15,580 triangle faces; no n-gons. Source/export: 3,145 component meshes, 74,170 vertices before engine splits. Approximate bounds: 17.86 × 17.86 × 70.45 m (Blender X/Y/Z), origin at ground centre. Scale and obscured rear details are reconstructed from photographs, not a measured architectural survey.

12 source PNG textures, each 2048 × 2048: four Base Color, four Roughness, four OpenGL Normal maps. Four Unity Metallic/Smoothness maps and four Unreal DirectX Normal maps are additionally supplied. Seven materials use constant PBR values. AO is constant 1; no baked AO map. One UV channel uses intentional repeated tiling, including coordinates outside 0–1; no unique lightmap atlas or UDIM set. No rig, animation, LOD, vertex colours or photogrammetry scan. This is a detailed landmark for desktop scenes and close views, not a universal mobile-budget asset.

Blender 5.0.1: editable source and explicitly triangulated export; Cycles day/night scenes. Unity 6000.6.1f1 / URP 17.6.0: two real prefabs, two demo scenes, 11 combined material meshes per variant, 207,419 render vertices, five approximate box colliders. Unreal Engine 5.8.3: one Static Mesh with 11 slots, 226,575 render vertices, two actor Blueprints and two maps. Nanite disabled; movable lighting, no baked lightmaps. Engine vertex counts differ because of import splits and tangent/UV seams; triangle counts match. Native engine support is limited to the versions and pipeline tested on Windows.

Night variants contain 89 realtime spotlights. Many overlapping lights are expensive; selectively disable distant or unseen lights for gameplay. The source night FBX also contains the light layout, but exchange-format imports do not reproduce renderer-specific lighting automatically. Each engine has adapted materials and light intensity; the previews are actual Blender renders, while images labelled Unity/Unreal are engine captures.

Minimum/maximum asset triangle count: 135,812 / 135,812 (two lighting variants of one model). Meshes per prefab: 11. Prefabs: 2. Demo scenes: 2. Materials: 11. Textures used in Unity: 12 PNG at 2048² (four colour, four normal, four packed metallic/smoothness). No custom runtime scripts or required third-party assets. Render pipeline: URP only. Supported Unity version: 6000.6.1f1. Includes documentation and simple collision. Dynamic night lighting must be adapted to your performance budget.
