UPDATE MAY 2025 - New and cleaner model! Showcase video: https://youtu.be/cuGn6Ayk7Rk

Highly detailed photogrammetry model of the Arc de Triomphe in Paris. One of the most iconic landmarks of the city, commissioned by Napoleon in 1806.

Reconstructed from 3372 ground-level images with Reality Capture. The model has been delighted and simplified using InstaLOD.

🌟 Key Features:

• Native Unreal Engine 5.4+ Format: Includes showcase level L_ArcTriompheParis_Showcase with Lumen lighting and post-processing setup.

• Nanite & Lumen Ready: Full Nanite continuous adaptive LOD and Lumen global illumination support.

• Accurate Collision: Custom Complex-as-Simple collision allowing players and cameras to walk directly under and through the monument archways.

• 2 UV Channels: UV0 for 8K PBR texture mapping, UV1 for lightmaps.

• PBR Textures: 8K Base Color, Normal, Roughness and Metallic (packed as ORM in the Unreal project).

• Normal map convention: the Unreal Engine project is ready to use (green channel flipped on import). The normal maps in the FBX, OBJ and GLB archives and in the raw high-poly version use the OpenGL convention (Blender, Unity, glTF): flip the green channel when importing them into Unreal Engine or 3ds Max.

📊 Technical Information:

• Number of Unique Meshes: 1

• Vertex Count: 219,567 (Triangles: 342,884)

• Collision: Yes (Custom Complex as Simple, hollow archways allowing full player movement)

• LODs: Yes (Nanite Dynamic Continuous LOD)

• Number of LODs: 1

• Rigged: No

• Rigged to Epic or MetaHumans Skeleton: No

• If rigged to the Epic or MetaHumans skeleton, IK bones are included: No

• Number of Characters: 0

• Vertex Counts of Characters: N/A

• Animated: No

• Number of Animations: 0

• Animation Types (Root Motion/In-place): N/A

• Number of Materials: 1 Master Material

• Number of Material Instances: 1 Material Instance

• Number of Textures: 3 in the Unreal project (BaseColor, Normal, ORM); 4 in the FBX, OBJ and GLB archives (Base Color, Normal, Roughness, Metallic)

• Texture Resolutions: 8192x8192 (8K)

• Supported Development Platforms: Windows: Yes, Mac: Yes

• Documentation Link: N/A

• Important/Additional Notes: Nanite enabled mesh with Lumen dynamic global illumination support. Features 2 UV channels (UV0: Texture Mapping, UV1: Lightmap UVs). Collision is configured as Complex as Simple so player characters can walk freely under the monument without being blocked. Real-world metric scale.

Perfect for high-end visualizations, game environments requiring authentic landmarks, or digital heritage applications.

Also included: a raw high-poly version with twelve 16K textures (6 Base Color, 6 Normal, OpenGL convention). It has not been delighted or cleaned: it is the first simplification exported from RealityCapture.
