Newbie here…
Seems like I follow the tutorial but every time I use slice curves, resmesh, I get all these weird artifacts on the edges of my cuts and when I move the pieces they seem to be still attached. The only way I can combat this problem is if I go into the Polygroup menu, use autogroups and it works there. However sometimes the edges are very messy, no matter how high I crank up the level in Dynamesh.
