Hi,

I was well into modeling a character for a short movie and I ran into into this weird bug:

whenever I convert an a poly object into subsurface division (alt+`) it works fine:

Before conversion:

After conversion:

so far so good.

The trouble begins whenever I undo that conversion (using 'z' key), the resulting shape is some sort of mix between poly and sub-d surface:

a closer look:

There seems to be some sort of residual cage underneath, you can see it when I move the vertices. That cage seems to be unselectable as well:

If anyone knows how to fix this, your help is greatly appreciated. I've pretty much stopped all modeling trying to find out how to fix this.

Thanks

select all your geo. open hypergraph. show input/output connections. delete history, delete all blind nodes.
