How to make mesh appear only on curves?

[Vancete]

Hi there,

I'm working with Curvy Splines to make a track generator. I want to make the race curbs (the thing that has a white-red pattern) only appear on the curve zones, and disappear on the straight lines.



I'm trying to make a script that makes that, but I'm not getting it working. The API reference is just that, but there aren't many script examples out there.

Any suggestion will be appreciated, thanks in advance
