RenderProduct Device Selection

When to Use

Use this skill when a scene, test, or example must constrain a RenderProduct to CUDA-visible GPU 0 or another explicit set of CUDA-visible GPUs, especially for multi-GPU CI or viewport picking.

Inputs

Resolve inputs in this order: existing repository files and referenced snippets, explicit user request, then broader agent context.

• Target API surface: Python, C/C++, USD, or a combination.
• RenderProduct prim path or scene file that needs a deviceIds restriction.
• CUDA-visible device index allow-list, usually [0] for picking or deterministic multi-GPU CI.
• Whether the pinning is authored in static USDA, inline USD, or an existing example/test scene.
• Repository source snippets referenced below. Treat these snippets as the API source of truth.
