SAMMLUNG
Sammlung — German for a curated collection. The word museums and scientific archives use for what they hold in trust.
A curated map of places worth looking when you need source material for conversion, preview, inspection, and shading work across Apple-platform USDZ workflows.
It mixes official USD references, glTF standards assets, institutional collections, reusable model libraries, and material-focused shader resources in one place.
Official and adjacent USD resources: reference assets, working-group repositories, and large sample scene packs.
OpenUSD Downloads — Assets
Official OpenUSD asset downloads, including well-known reference scenes and sample datasets published alongside the spec.
USD Working Group — Assets
Cross-tool USD assets assembled by the USD Working Group for interoperability and ecosystem alignment.
NVIDIA Omniverse — USD Content Sample Packs
Downloadable USD content packs from Omniverse docs, positioned as reusable sample scenes and composition references.
SideFX Learning Library — Content
Houdini learning content and downloadable sample scenes relevant to procedural pipelines and USD-adjacent workflows.
Disney Animation — Moana Island Scene
A large-scale research scene released by Walt Disney Animation Studios and widely referenced in rendering discussions.
Apple-native viewing and delivery references centered on Quick Look and USDZ presentation.
glTF reference catalogs and sample assets maintained by standards bodies and rendering research teams.
Khronos glTF Assets
A Khronos-maintained index of glTF assets and related resources across the web.
Khronos glTF Sample Assets
Official sample assets covering common glTF features and exchange scenarios.
Intel Graphics Research Samples
Rendering research sample scenes and benchmark environments commonly used in graphics evaluation.
Museum, archive, and scientific collections with scanned artifacts, specimens, and heritage objects.

General-purpose model libraries with reusable production assets for lookdev, interaction, and game workflows.
Material references, shader playgrounds, and measured-value resources for surface evaluation.
Physically Based
Reference data for physically based materials, including measured values and surface characteristics.
MaterialEggs
Material-focused reference assets designed to compare shader and rendering behavior across surface setups.
OpenPBR Shader Playground
OpenPBR-focused reference material and shader playground assets for evaluating the emerging shading model.
