Hi all,

So I’ve noticed the lerp (Rotator) node has an option to use shortest path, but not the Finterp to Constant? I was just wondering if there was a way to do this as I have an object that once passes 180 degrees, will reverse its direction and do an almost 360 until reaching its goal.

I noticed this post asked a similar question but the answer was in code… It did mention quaternions and I tried researching them but couldn’t understand. So any help would be appreciated.
