I was working with the Hexagon to tweak an already existing object and I ended losing all the material zones info in the process.  Since I still have the original object with all the material zones, is there any way I can transfer those zones to a tweaked object? 

I instead tried to load the tweaked object as an morphed target, but for some reason it's not letting me go this route (even though I didn't add or delete any vertices).  And some material zones are really complicated to select them manually so I don't think I can get get all the polygons by this way.

Is there a way I can open the object in a text format and copy the zones?  Or how about any programs that can handle this?

Thanks in advance for any help.
