Incorrect mesh alignment after extrusion on curved path

[_Aka_]

Hi,

Try setting all the parameters related to the spline/mesh details to a very high value, to see if this solves the issue. If it doesn't, please send me a scene with a reproduction case and I will check it.

Here is a list of the parameters I am thinking of:
Curvy Spline -> Cache Density
Curvy Spline -> Max Points Per Unit
Input Spline Path -> Use Cache (try with both values)
Shape Extrusion -> Path -> Resolution
Shape Extrusion -> Path -> Optimize (set to false)

I hope this helps.
