Hello Max,
I am currently investigating a universal way to do this, and wanted to provide you with some possible helpful resources I found.
An older Unreal thread references this other thread where a user copied the points of their spline for use later.
There is a more recent one here that delves into that same topic, by use of a library they created that may give some good ideas.
I’m continuing to look into the documentation to see if there is any other in-house way to do this.
Let me know if any of this helps out!
Thanks,
Kyle B.
