I don't use MD2 because you cannot access it's Vertices etc. but currently I am not sure if it's also completely unpickable.
All I know is: if you use animated Meshes of the 3DS or X Format, you need to make all of its mesh children pickable. I made an example for setting Children properties recursively (eg. for AntityAlpha), the same way it would need to be done with EntityPickMode:

You can try it, maybe it helps.
