If you use save object as
you can chose gamestudio A6 model direct
but by my experience
is better if you export your model by part
(sample if you have a door with a window export
the object in the same place (gamespace) and load
if med first one and appen the other (in med you can added
multiple objects to one model)
then the independent textures are good
if you combine the two objects with diferent textutes
then gamespace export bad the model
