you want to move a camera or an object along the spline?
you don’t need so many points!
use this two nodes (one for position and the other for rotation)
be sure to have constant velocity ticked and coordinate space in WORLD
and setWorldLocation and setWorldRoation to the object you want to move.
time 0 is the beginning of the spline and time 1 is the end of the spline.
you should remove like 90% of those vertices because are useles
