PBR
PBR (physically-based rendering) is a shading model that defines surfaces with albedo, roughness, metallic, and normal maps — the standard for cross-engine architectural materials.
PBR (physically-based rendering) is a shading model that describes surfaces with a small set of physically-meaningful texture maps — albedo (base colour), roughness, metallic, and normal — instead of bespoke per-engine shader graphs. It's the default material spec for modern game engines, web 3D, AR, and Renovato's 3D outputs.
In context
PBR's promise is engine-portability: a PBR material authored once renders consistently in Unreal, Unity, Three.js, Blender, and Apple's RealityKit. For architectural visualization, this means a wood-floor or concrete-wall material from a Renovato 3D export looks the same in every downstream tool.
In Renovato
Renovato's image-to-3D mode bakes PBR materials by default — albedo, roughness, metallic, normal — ready to drop into Unreal, Unity, Blender, or any PBR-aware renderer. The material maps are bundled into the GLB / USDZ so there's nothing to wire up post-export.
