Orientation in 2D

[_Aka_]

I learned that you can't instantiate and rotate a control point in the same step since there are some functions (GetOrientationFast) that needs the cache from the spline.

Since you are using Curvy 2.3.0, I am getting back to that quote. When you say "I learned", do you mean you read this on the forum, or you found an issue in your current version? If the latter, I am interested in more details.

So it seems like when the control points are pulled from the pool, their rotations are not being reset.

You are right. I will modify this in the next version, so that pooled control points will have default transform.
