Splines (for paths) Replication.

I tried some of Tegleg’s extensive code for an easy fix to get a vehicle working on a spline, rather than use pathnodes and have a bot vehicle go where it wants.

Works great offline, the bot follows the spline path, but only offline. Online the vehicle doesn’t show up at all.

Does anyone know if splines can be used online? Are spline paths a definite NO online like Crowds? Naturally I’ve searched online for mentions of spline paths. I’ve looked into UT spline code too but nothing re replication. Online there are comments on road splines which have been problematic.
