Why Convert USD to GLTF?

USD powers Hollywood VFX pipelines. glTF powers the web. Convert Pixar scene data into assets ready for interactive 3D on any platform.

VFX to Web

Convert Pixar USD scenes from Maya, Houdini, or Katana to glTF for web-based 3D viewers, interactive configurators, and AR product previews.

Composition Flattening

USD uses complex scene layering and references. Our converter resolves composition arcs and flattens the stage into a single exportable scene.

PBR Conversion

USD's Preview Surface materials (UsdPreviewSurface) map to glTF PBR metallic-roughness workflow. Base color, metallic, roughness, and normal data transfer accurately.

Real-Time Rendering

glTF is the standard for three.js, Babylon.js, Unity, Unreal, and Apple AR Quick Look. USD scenes become interactive real-time assets on every platform.

About USD to GLTF Conversion

Why convert USD to GLTF?

USD (Universal Scene Description) is Pixar's open-source framework for 3D scene composition, interchange, and collaboration. The backbone of modern VFX and animation pipelines at Pixar, ILM, and major studios. It supports scene layering, variants, references, and complex shading networks. glTF 2.0 is the Khronos Group's standard for efficient real-time delivery, compact, GPU-friendly, and supported natively in web browsers, AR platforms, and game engines. Converting USD to glTF bridges the gap between high-end VFX authoring and interactive real-time deployment.

What is preserved during conversion?

Mesh geometry, UV coordinates, vertex normals, and object transforms are extracted from the USD stage. UsdPreviewSurface materials are converted to glTF PBR metallic-roughness workflow with texture references preserved. Scene hierarchy is maintained. USD composition arcs and references are resolved/flattened. Complex USD features like variant sets, extensive layering, and USD-specific shading networks (MaterialX) are simplified. Only UsdPreviewSurface is converted to PBR.

How to use the converted GLTF file

Load the glTF with three.js GLTFLoader, Babylon.js, PlayCanvas, or Google Model Viewer for web deployment. Import into Unity, Unreal Engine, or Godot for game development. Convert to GLB for single-file CDN hosting. The glTF output is ready for all modern real-time 3D applications.

How to Convert USD to GLTF

Three steps to transform your Pixar USD pipeline scenes into web-ready glTF assets.

1

Upload Your USD File

Drag and drop your .usd or .usda file. USD scenes from Maya, Houdini, Blender, Katana, or Nvidia Omniverse are supported. Free tier: up to 50MB.

2

Flatten & Convert to glTF

Our cloud engine resolves USD composition arcs, flattens the stage, extracts mesh/materials/scene data, and writes glTF 2.0 output with PBR materials.

3

Deploy to Web & AR

Download your glTF and load into three.js, Babylon.js, or convert to GLB for CDN hosting. Files auto-delete from our servers within 1 hour.

Frequently Asked Questions

USD (Universal Scene Description) is Pixar's open-source scene composition framework it supports layering, variants, references, composition arcs, and deep shading networks. It's the standard for film and VFX production pipelines. glTF 2.0 is the Khronos Group's web delivery standard compact, efficient, GPU-optimized, and supported natively in browsers, AR, and game engines. USD is for authoring; glTF is for delivery.
Yes. You can convert up to 3 files per day for free with files up to 50MB each. For unlimited conversions, 500MB files, and batch processing, upgrade to Pro.
USD composition arcs (references, payloads, inherits, specializes) are resolved and flattened during conversion. The glTF output contains the fully composed scene with all geometry, materials, and transforms combined. Variant sets are not preserved only the default variants are exported.
Yes, UsdPreviewSurface materials are converted to glTF PBR metallic-roughness workflow. Diffuse/baseColor, metallic, roughness, normal, occlusion, and emissive channels all transfer. Advanced USD shading networks (MaterialX, UsdShade) are simplified only UsdPreviewSurface is supported for PBR conversion.
USD exports are available from Autodesk Maya (with USD plugin), SideFX Houdini, Blender (USD add-on), Foundry Katana, Nvidia Omniverse, Pixar's Presto, Apple's Reality Composer, and other VFX tools. USD is the industry standard for scene interchange in film, animation, and visual effects.
