help with blend shapes in Maya

I'm using Maya 2013, creating blend shapes for a facial rig and one of my blend shapes has some extra verts. I can't seem to find them tho, is there a way to compare two models with similar topology to see where I screwed up?

The best way to fix this is to first determine what caused those extra vertices to be created. It's odd that it would happen in the first place. Chances are the point order of the mesh has changed, so removing the vertices might not fix the problem.

I'm assuming the mesh is quite dense? Or finding the problem verts or just recreating the blendshapes might be the easiest way to fix this.

You can try selecting all the vertices of the mesh and deleting to get rid of duplicated verts or verts that lie on a single edge.

You can also set your merge threshold to .0001 and try merging all selected vertices as well.

You can use:

size(`ls -sl -fl`);

To get the number of selected verts to compare the base mesh with the problem blendshape.

Generally this will happened if you didn't merge any vertex , or else you have a tri or 5-sided face. try to find out those.

you can found the tri or 5 sided faces from "selection using constraint" option from select menu.
