NCP-OUSD case studies
NCP-OUSD · Put your knowledge to work in context.
NCP-OUSD is a professional certification for developers, technical directors, and pipeline engineers who build and maintain OpenUSD-based content pipelines. It validates that you can reason about USD as a data model and composition engine, not just click through a DCC tool. The exam spans eight domains: core fundamentals, stage composition and layer stacking, the schema system and schema development, Hydra rendering and the scene index, data exchange and interoperability, asset structure with instancing and performance, pipeline integration and tooling, and validation, debugging, and troubleshooting. Composition carries the heaviest weight, followed by fundamentals, schema work, Hydra, asset structure, pipeline tooling, and troubleshooting, with data exchange slightly lighter. The NCP-OUSD case studies are 5 cases and about 4,148 words.
