A collection of 16 highly realistic paving stone assets captured and reconstructed through a rigorous polarimetric photogrammetry pipeline.
Every surface has been physically calibrated to deliver ground-truth PBR response under any lighting conditions—completely free of specular contamination, baked shadows, or guesswork.

Advanced Polarimetric Capture Pipeline: Multi-Angle Polarimetric Scanning: Each individual stone was captured using 432 photographs (4 polarization states per camera station: 0°, 45°, 90°, and 135°).

Pure Cross-Polarized Diffuse: Reconstructed from 108 cross-polarized images, completely eliminating specular highlights and glare for true surface albedo.

Stokes Vector Roughness: Surface roughness mathematically calculated from Stokes parameters, isolating microfacet scattering directly from physical light behavior.

DoLP-Derived Specular: Specular intensity derived from the Degree of Linear Polarization (DoLP), accurately mapping physical Fresnel reflectance across the surface.

SfP (Shape from Polarization) Normals: High-frequency surface normals computed via Shape from Polarization, resolving micro-geometric details beyond the limits of standard photogrammetry.

Features:
16 Unique Paving Stone Static Meshes with ~3K triangles per asset.
Virtual Textures (UDIM workflow) for high-fidelity multi-tile UV coverage with 4096x4096 Tiles.
Packed ARMS texture format (Ambient Occlusion, Roughness, Metalness, Specular).
- Diffuse (Cross-polarized / sRGB)
- Normal (Shape from Polarization / Linear)
- ARMS (R: AO, G: Stokes Roughness, B: Metallic, A: DoLP Specular / Linear)
Nanite-enabled meshes for optimal performance and infinite geometric detail.
Custom simplified collision hulls pre-configured for every mesh.
Master Material with Material Instance setup following Epic's official standards.
Overview demo level included.

*Object nº02 was made using a simpler workflow using only a cross polarized dataset, without Stokes, DoLP or SfP and is included as a bonus asset
