Right, the way read it was can't just replace the TO field of a ROUTE, I have to replace the entire ROUTE. <br>
Same with MF field, if I want to update just one SF value, I have to send the entire MF field (?). <br>
Thanks,<br>

I don't want to discourage anyone from trying any idea in programming, or even discuss potential design of a system which take the current X3D as a jump off point for a much different type of architecture, but I judge that making the ROUTE statements in a scene description modifiable via events. should be far over the horizon for the X3D development and maintenance team, and to be blunt should be pursued in a separate forum such as a github project or Slack channel.<br>
<br>
We have several X3D viewers which are open source and lend themselves to being forked and modified to allow modifying the ROUTEs in real time, but these projects should be identified as no longer X3D viewers but a different (possibly much better, I allow) 3D authoring system.<br>
<br>
I refer anyone to an interesting document on the design of VRML 2, this document is at <a href="https://mitra.biz/vrml/vrml2/sgi_design_15jan96.html" rel="noreferrer" target="_blank">https://mitra.biz/vrml/vrml2/sgi_design_15jan96.html</a> . It gives specific reasons for the design and abilities of ROUTEs which I think are still valid.<br>
