attach 2 objects
 

i'm currently doing the joan of arc tut and having troubles attaching the head to the body... in low poly it seems ok, but if i smooth it, there is a hard edge :mad:

and the low...

check the following:

Normals - The normals of both objects may be opposite each other. Use the edit polygons > normals > commands to fix.

Merged Vertices - check to see if the vertices in that area from the two objects have been merged together.

Doubled geometry - check to see if you have doubled faces or edges.

I've got a mirroring and attaching video on my site that may help with this. Not necessarily the mirroring part, but the attaching.
