Hello their, i have a problem with border edges, the edges still don't seem weld, even if i delete the 2 quads on eatch side of the border edge, i extruded the edges again, merged them together, and again i get that border egde. In the past it always worked when i deleted the 2 quads that create this border edge, and now i can't remove the not merged edge. Those somebody have a idea thx in advance. Woops i posted in the animation section, my bad, i needed the modeling section.
