Hello, I'm new here and pretty new to Maya as well. I keep getting this problem whenever I convert a SubDiv model to Polys.
I set the Tesselation method to Vertices, the Level to zero, and and the Original Object to replace, and the conversion seems to go allright, but then when I start pulling the vertices on the resulting polygon, things get weird. It seems like there appears to be some sort of "invisible mesh" over the poly object. Like I'll select a point and move it, but what moves instead is another point that was right over the one I selected. The edges that extend from that point are connected to other points just like it, and the faces are completely transparent. How can I fix this?

Thanks!
