if that guy really managed to recreate early r15 in 2007 only using cframes, then it's probably possible to recreate modern r6 using only cframes (but that would prob be almost as hard as how hard it was for early r15 in 2007), and if it would be public, i wont have to resort to using old roblox anims to even have animations in the 2016 studio client again! (or just make a converter that converts roblox animations to cframe that would work if you insert it inside a player)
