Extend OVRTX Lighting and World

When to Use

Use when adding Blender light fields or families, dome/World policies, topology classification, typed USD attributes, depsgraph routing, retained edits, or tests.

Boundaries

• Change only add-on code and tests, using documented runtime interfaces.
• Keep initial authored values and live edits on one conversion policy. Do not add a render-only correction that disagrees with interactive updates.
• Route family, graph, texture, assignment, or prim-presence changes as topology. Use typed value writes only for fields whose USD prim and attribute already exist.
• Fail closed on missing, ambiguous, wrong-family, or unauthored USD targets.
