Spline mesh generating additional geometry

Hey all, I’m using a Spline Mesh Blueprint to generate some train tracks. It works for smaller segments, but starts generating additional geometry as it gets bigger. For example, here’s a small one:

At a certain part it starts freaking out:

And then it gets really weird:

Any idea why it’s doing this? I’m basing my Blueprint off this tutorial: https://www.youtube.com/watch?v=eKIiWa19EMI

EDIT: After doing some experimenting, with just a beginning and end point it seems the issue pops up when the length of the spline is > 2x the length of the object being instantiated. If I add a third point, the issue appears when it’s 3x the length of the object, with a fourth it becomes 4x etc. Still not really sure what’s going on, but making some progress…

Ugh, so turns out there’s a section at the end of the video about limiting the length of the tangent and doing that fixed everything. I guess the lesson here is always finish the video, even if you think you’ve got it :joy:
