Get location at distance along spline inaccurate with curved tangents

Hey,

I’m using the construction script to distribute chain links along a spline.
Everything works great with linear tangents, but once i add some curve to the equation, the links no longer lign up perfectly. The discrepancy is not huge, but still clearly visible. I figure this must be due to inaccuracy within the “Get Location at Distance Along Spline” function when using curved tangents. does anyone know if there is a workaround to this ? maybe some way to compensate with math?

I noticed the same thing. The distance it returns is the distance of the spline, which can stretch. The way I worked around this was to walk something along the spline and just measure the distance traveled in world coordinate space.

Gives a pretty accurate measurement, but it is a dirty workaround and computationally pretty heavy with a very high step count.
