The relocates composition arc provides non-destructive namespace remapping of prims from remote layer stacks to new path locations in the local namespace. Relocates enable reparenting or renaming of prims in situations where direct editing of the composition source would be destructive, affecting all other contexts that reference the same scene description.
Relocates address a fundamental limitation in USD composition: prims with underlying PrimSpecs from composition arcs cannot be directly reparented without modifying the source scene description. While it is technically possible to reparent composition source prims directly, such changes are destructive and would affect all other instances that share that scene description.
