I've created an arm and a hand separatedly, then I joined them, after that, I took the vertices and connected them together to create new faces. Everything looks fine with the basic shape

normal mesh

But once I apply some subdivision as a modifier then some really easy to spot lines appear :( basically on those two areas that I've merged together, what can I do to fix this? thanks!


  • $\begingroup$ I've run into this several times - it's always a relief to remember those sneaky internal edges/faces! $\endgroup$

I found the solution, two edges were automatically generated within that shape that was causing this problem :)! edges disolved, the issue disappeared. thanks anyway!
