I have a question about this.
Since it will be impossible to properly have a working infinite loop of this, does it ever slope back down to the ground at the ends of itself?
I understand that for it to have looped realistically and seamlessly like before, there were no points where it went down all the way to the slate-ground and become flat so it could loop again.
How are you going to deal with that, will you be smoothing the edges and make them meet the ground at one point?
