Generator Shape Extrusion Range/Lenght precision

[UsernameHed]

My Percent is your equivalent of your TF. So TF is relative to the lenght of the Segments in the spline, so it's not what I wanted.
So for my CustomSplineController I use only Distance, with is good for me, and when I need it, I can convert it to TF with Spline.DistanceToTF.

But what I needed for that one is more something like Spline.DistanceToNormalize().

Thanks you, the probleme is solved, and I understand more and more your base code as I progress
