Switch the root model
Understand whole-model switching and its current authoring status.
Root-model switching is intended for an option that changes the entire visual foundation, not a single material or detachable part.
Current Editor status
SET_MODEL exists in the GraphQL operation enum, but the current Editor mappings panel does not edit it and reports hydrated unsupported operations. Use the normal root-model assignment for one product model. Do not document or design a production workflow around an Editor Set model control until that control and its value contract are implemented.
If whole-model switching is required today, verify the exact API authoring and renderer contract in your deployment. Consider separate products or revisions when they better express distinct catalog items.
Verify
Before enabling a custom implementation, test camera framing, target compatibility, material bindings, component placement, asset loading, commerce mappings, and switching back to the previous model.
