Hey, LROG -- yes, I'm sorry to be late answering, but obj2cr2 will give you a conforming dress rig.  :-)  But looks like you already figured all that out.  Your dress looks great!

A tip about dresses/obj2cr2...if you haven't learned it already...make the thigh bones "ghost."  Rename them.  That way, you won't get wonkiness in the skirt when the legs move.  Ugly mesh bending...unless you can smooth, with the weight map brush.  I just make the thighs "ghost" then bend the skirt with the "handles." :-)

I love me some Modo!  :-)
