I have to assume that the algorithyms for various tool options and uses in MED may be mostly taken up and so limiting, via license prices, for incorporation as I dont see why MED is still the primitive modeller that it is. Even old Amapi is fantastic compared to MED!
But its got everything anyone needs to make assetts directly for the engine to use without the laborious process of importing/exporting.In short its perfect for new starters in GStudio but a drag for advanced modellers.
My personal favourite is MAYA (..cant afford it but started learning on MAX) but Dan talks good about MODO ( the demo wouldnt load up for me on my system so Im not buying it)and Silo gets good reviews too.
For an animation pipeline when I can be bothered loading it up is my old Poser 4 (cant afford to upgrade that one either..) where poses are saved out (exported via obj, 3ds etc) as key frames then set up in MED, good trick
