usd-projection

usd-projection is a Graphics, 3D & shaders skill for AI agents, published by LunCoSim in the lunco-sim repository on GitHub. Skillspace rates usd-projection D (55/100) and it passed the safety scan; the rating is based on static analysis only.

How USD becomes the running 3D world in LunCoSim, and how to extend that translation. USE THIS SKILL whenever you are working ON the USD layer itself rather than authoring a scene with it: "add support for <USD prim type / new attribute>", "my attribute is being ignored", "the edit saved but nothing moved on screen", "why didn't my change undo / persist / replicate?", "how does a prim become an entity?", "where do I read this attribute?", "should this be a `lunco:` attribute or a standard schema?", or any time you're about to add a field to a prim, touch `lunco-usd*`, or write ECS state that ought to live in the document. Also trigger when tempted to "just set the component directly" or to accept a second spelling of an attribute so a file loads. (For AUTHORING scenes over the API — spawn/move/load — use `build-usd-scene` instead. This skill is the machinery underneath it.)
