USD → GLB · Online Conversion Guide
Flatten layered/referenced scenes to a distribution‑ready format Enable fast loading on web and mobile Standardize into glTF ecosystem for compression and PBR handling
USD: USD (Universal Scene Description) by Pixar supports complex scene layering, references and collaboration; a modern core for DCC/asset pipelines.
GLB as the target format: GLB is the binary form of glTF, ideal for web/mobile real‑time delivery with small size, fast loading, and mature tooling.
Practical tips: Bake complex layering/references when necessary; Ensure material extensions map to glTF‑supported PBR.
Typical scenarios: Cross‑team asset integration, virtual production, scene assembly.

FAQ
Q: What information may be lost from USD to GLB?
Parametric features/constraints/history become polygon meshes; verify materials and textures.
Q: How to reduce size for USD → GLB?
Remove hidden parts, lower tessellation where acceptable, compress textures, enable Draco, merge materials.
Q: Batch or very large models supported?
Use 3D Tiles tiling for massive assemblies; consider splitting by hierarchy/area.
Q: Can I further edit after converting?
After converting to GLB, geometry is mesh-based; you can clean meshes and tweak materials, but parametrics are not preserved.
