Yes, that’s what I’m trying to do. I the blueprint in the first post, I’ve managed to calculate correct position of points, the only thing left are tangents. Currently, the tangent of “Spline” is connected directly to “Spline1”, but I guess I need to calculate the correct tangent according to the offset. I’ve found something about calculating normal of tangent, but I’ll be honest, this kind of math is difficult for me to understand - answer from Joltz at link: https://www.reddit.com/r/unrealengine/comments/529wa8/question_spline_location_offset/
