Regarding the scaling thing, what has me baffled is the fact that the OBJ file imports into POSER at the proper size and then exports from POSER into MD2.0 appropriately. Moreover, when I export the MD2.0 Avatar into Max using Collada, it comes in appropriately scaled (although she is lying on her back due to axis reversal). I can then convert the imported Avatar into an editable mesh object and when I export her back into MD2.0 I get nada. So, if it is a scaling issue it´s a pretty weird one.
Similarly, the very same OBJ file from POSER that imports fine into MD2.0 comes into MAX just fine at the proper scale.
Pretty strange.
