🔖 Event Graph ROUTE Table entries with 2 ROUTE connections, showing X3D event-model relationships for this scene.
Each row with a ROUTE statement shows an event cascade that may occur during a single timestamp interval between frame renderings, performed as part of the X3D execution model.

ProtoInstance Rotor |
No direct ROUTE connection found for events to/from this node. This ProtoInstance contains SFNode/MFNode fieldValue declaration with direct access to other nodes, and thus has potential to produce run-time animation. |
