• 168 unique visual meshes across the production prefabs.
• 9 referenced materials using Universal Render Pipeline/Lit.
• 6 unique shared base-color textures.
• 1 URP demo scene and a modular snap tool.

• Enclosed Straight 01: 2,796
• End Platform 01: 3,728
• Escalator 01: 6,116
• Lift Tower 01: 5,552
• Long Straight 01: 11,292
• Short Straight 01: 5,620
• Stair 90 01: 10,444
• Stair 90 Right 01: 10,444
• Stair Straight 01: 8,788
• Straight 01: 9,620
• T Junction 01: 5,688

Total: 98,640 triangles for one instance of each module.
Average: 6,576 triangles per module.
Minimum / maximum: 1,884 / 11,292 triangles.

Textures and materials
All six textures are PNG base-color/albedo maps:

• Concrete Light: 512 × 512
• Railing Galvanized: 512 × 512
• Roof Muted Sage: 512 × 512
• Steel Painted Dark: 512 × 512
• Walkway Dark: 512 × 512
• Escalator Tread Ribs: 128 × 128

Texture use per module:

• All 15 modules use Concrete Light, Railing Galvanized, Roof Muted Sage and Steel Painted Dark.
• Building Connector, Enclosed Straight, End Platform, Long Straight and Wide Platform use these four textures.
• Corner 90, Lift Tower, Short Straight, Stair 90, Stair 90 Right, Stair Straight, Straight, T Junction and X Junction additionally use Walkway Dark.
• Escalator uses all six textures.

Textures are shared between modules. No normal, metallic/smoothness, ambient occlusion, height or emission textures are assigned to the production materials. Glass BlueGrey, Escalator Comb and Escalator Rubber materials have no assigned textures.

LOD, rigging and animation

• LODs: no LODGroups configured in the production prefabs.
• Rigging: no SkinnedMeshRenderers in the production prefabs.
• Animation: no Animator or legacy Animation components; 0 referenced AnimationClips detected in the production prefabs. These counts do not cover procedural or runtime-loaded animation.

Colliders and UVs

• 220 MeshCollider components across the 15 production prefabs.
• Collider helper geometry is excluded from the visual triangle counts.
• Dedicated secondary UVs for lightmapping.

Scale and compatibility

• 1 Unity unit = 1 meter.
• Target clear walkway width: 3.5 meters.
• Target elevated walkway datum: 5.5 meters.
• Tested with Unity 2022.3.62f2 and URP 14.0.12.
• Statistics collected using the Windows 64-bit build target; listed texture dimensions match both source and imported sizes.
