Spline points, relative locations

I am working a bit with splines, and I got right now a spline with multiple points that are set in the constructionscript. During gameplay 1 point in the middle of the spline is moving, and I want half of the spline to follow relatively. How would I do that? if i save my relative spline positions on event begin play and add them in an array they will still be the same position as before…

Please help :slight_smile:
