SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Binding materials to prims at runtime eases on-the-fly visual updates in USD scenes, enabling dynamic material assignment, changes, or swaps without recompiling assets.

Core Features & Use Cases

Identify geometry prims and target material prims in a loaded USD stage.
Write the material:binding relationship so a geometry prim binds to an absolute material path.
Supports runtime updates via USD, Python, or C/C++ runtime APIs.
Typical use cases include changing appearance during exploration, swapping materials for variants, or applying sensor-facing textures.

Quick Start

Identify the geometry prims in your USD scene and apply a target material via the material:binding relationship on the geometry prim.

FAQPage Schema

How do I bind materials to USD prims at runtime?▼

To bind materials to USD prims at runtime, write the material:binding relationship to geometry prims using absolute material paths via Python or C/C++ runtime APIs.

Can I swap materials on geometry prims without recompiling USD assets?▼

Yes, binding materials at runtime enables dynamic material assignment and swapping on geometry prims in loaded USD stages without recompiling assets.

How does the material:binding relationship work in Omniverse USD scenes?▼

The material:binding relationship links a geometry prim to an absolute target material prim path, ensuring runtime visual updates apply correctly within the USD stage.

What is the best way to apply sensor-facing textures to USD geometry at runtime?▼

Applying sensor-facing textures at runtime involves identifying target geometry prims and writing the material:binding relationship to bind absolute material paths via Python APIs.

Do I need Python APIs to change material variants on USD prims dynamically?▼

No, you can change material variants dynamically by writing the material:binding relationship to geometry prims using either Python APIs or C/C++ runtime helpers.

Why use absolute prim paths when binding materials to geometry in USD?▼

Using absolute prim paths when writing the material:binding relationship ensures the geometry prim correctly targets the intended material prim for reliable runtime updates.
