This is a ported cs2 behaviour from rex to cs3 runtime. (Spline-Path-Movement).
Open you a lesson from rex?
Yes, can you have a lesson without Rex?
The example-files from rex not work with the plugin. I have changed the plugin-id (for later own changes on the plugin).
But i can make a example-file for you.
I will be extremely grateful, because I could not fully understand how the plugin works.
