Originally posted by legendofzombi You're problem from what i can see is A: the verts on the mirror plan of the original geometry arnt all lined up whit the central axis that you are mirroring across. and B, your pivot point for the mirrored geometry needs to be aligned up with the o coordinate for the axis which you are mirroring across. That should fix the problem you're asking about G-man I have the vertices aligned verticaly along the y-axis. So what you are saying cannot be the problem.
