Help !, Maya created double faces over an entire level !

jimpaw · Mar 2011

I just did a huge lowpoly level. To my surprice i see that Maya has created double faces all over the place ! I did a merge on all the verts in the scene wich took down the amount of vertecies to half, but somehow the faces remains.

I have tried to mark all the faces and delete but then Maya deletes all faces.
I have tried to select one face and then use the "grow selection with < + shift" still deletes all the faces. cleanup doesn't work either...

Can someone help me ? , is there a script that can fix this ?

here's a small snippet of python code that will tell you if one of the selected faces is a duplicate:

from maya import cmds as cmds
l = []
for f in cmds.ls(sl=True, flatten=True):
    cmds.select(f)
    cmds.polyInfo(fv=True)
    v = cmds.polyInfo(f,fv=True)[0].split()[2:]
    for x in l:
        if set(v) <= set(x):
            print '%s is a double face' % f
    else:
        l.append(v)

THNKR, could you please update that script so it selects the duplicated faces so they can be deleted with one click, that would be quite a helpful script for a couple artists I've met.

Here is my reply from the duplicate thread, which does exactly what you want without any scripting:

elementrix wrote: »

mesh - cleanup... - then select matching polys and uncheck everything except "Lamina faces (Faces sharing all edges)" Hit cleanup, now maya will select 1 face for each double face, then you can press delete.

You could also let it cleanup straight away but I always prefer to check what it had selected before I actually delete the stuff.

Hope it works

(Didn't try out the script but I guess it's the same)
