First and foremost, the asset is spectacular. I wish I had known about it sooner could've definitely helped with a game I was developing. I think you should consider uploading it to the ue4 marketpalce for it to gain a bit more traction.
But I digress, I went over the tutorial explaining the math behind it which I greatly appreciate you explaining, and was wondering, if it would be possible to extend the functionality of it to support 4 players. Is this something that you thought of by any chance ? Or something you can add with ease if possible ?
I'm asking because I'd like to purchase the asset myself, but only if adding the functionality is possible.
