Ever struggled with calculating vehicle speed while animating over a spline?

On every project where I had to animate vehicle at the exact speed in km/h or knots I had to calculate difference between start and end point, do the math and still if an object travels on a curved spline calculation would be incorrect. That’s why I’ve created a Blueprint which solves this problem for you and takes you even step further so that you can add modifiers to your animation.

Now I can animate any type of vehicle or flocks basically in a minute.
