combining-scene-with-runtime-prims

What problem does it solve?

ovrtx docs tests often need to combine a base USD scene with doc-specific prims such as RenderProduct or RenderVar, without duplicating the entire scene. The inline root layer approach keeps the base content intact while adding needed prims in the same root layer.

Core Features & Use Cases

• Inline root USD string pattern that uses subLayers = [@/path/to/base_scene.usda@] to incorporate the base scene content and author the extra doc-specific prims in the same root layer.
• Works with Python open_usd_from_string() or C ovrtx_open_usd_from_string() to load the single composed stage for testing.
• Reduces test snippet complexity by enabling a single-root, composed scene for documentation examples.

Quick Start

Load an inline root USD that sublayers the base scene and any runtime prims, using a string loaded with open_usd_from_string (Python) or ovrtx_open_usd_from_string (C).
