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


Additional guidance on X3D animation can be found in the 10-Step Animation Design Process and Event Tracing hint sheets. Have fun with X3D! 😀
