Originally posted by Jr.Who Well, before you dupe it over, make sure that all the verts are in the middle. When you merge them, set the merge distance really low (it might taker a couple tries to get it right), then just select ALL the middle vertices and hit merge. Make sure you look around to see if any vertices that you didn't want merged were merged. Hi again, i found the answer in the mirror treshold properties at inputs when i put in 0.001 it works fine thx for helping ieoie out......
