Mirror Face anomaly


#1

This is my first week using wings (I’m a max user by profession), so bear with me if the question seems a little obvious.

I’m using the virtual mirror, but when I move centre vertices i’m getting an extra face appearing along the centre line (see attached image). I assume I’m doing something wrong with the way I’m setting up the mirror or the way I’m moving the verts.

I’ve tried searching the forum for a similar problem, but haven’t come up with anything (thus the post!).

Any ideas?:smiley:

As far as I know you can’t play with the center line verts without distortion.

If you want to make adjustments to the center line verts, BREAK the mirror…make your adjustments then recreate the mirror once done.

Ouch… okay. I’ll give it a whirl.:slight_smile:

Erilaz, you certainly can work on the mirror plane verts with virtual mirror on, obviously you have to be careful not to move them away from the mirror axis and some tools behave slightly differently on the mirror axis I believe.
Without seeing the model it’s difficult to tell what’s happened here. It looks like you’ve accidently created an extra poly on the mirror plane. This shouldn’t happen with a properly constructed model.
Create a cube, select all edges and make them hard, subdivide the mesh twice. Now cut it in half and mirror. If you select a vert or pair of edges on the mirror plane an move normal you’ll see the mirror behave correctly with no anomolous faces poking out.
I’d try breaking the mirror and investigating the mirror plane. My guess is you have one or more additional faces that can be deleted. By the way, it’s worth selecting all faces on the mirror plane and dissolving into one big n-gon. Multiple polys on the mirror plane can cause problems :o) - Baz

One of the great joys of using VM - imo - is the fact that elements on the VM stay on the mirror plane - and as such, you can get a constrained 2 axis planar workaround (just dump the virtual half after you’ve finished messing)

(Try using Tweak on elements that are partially (or wholly on the VM plane to see what I mean :))

As baz says - ensure the VM face is a single one - one of the ways it’s possible to (easily) produce multiple ones - without realising - is to use Extrude, rather than Extrude Region.

Using the latter option should not result in extra edges being formed on the mirror plane.

It’s possible it might also be a display artifact, btw.

Thanks for the info! Much appreciated. I’ll try those techniques out.:wip:
