I think so too PHeMoX. MED should be able to do everything needed for editing before improving built-in Import/Export features. 3rd party people always seem to find a way.

Development could consider making the MDL file more versatile in its construct to optimize Imp/Exp in accepting one particular format that is favored when sharing models between all the programs. This might help to produce more consistant results rather than trying to accomodate conversions for many formats.

I'll be needing to make detailed humanoid models and skins in a year or two, hoping that MED will be able to be used for this purpose.

From what I understand it has some limitations in the UVmapping power for such things?
