I have to much problems with truespace 7.5 for use with 3dgamestudio the x exporter not work very well (but that from ever)

and with the gamepak the think not goes better (the med support is very bad)

I waiting and hope the next version 7.6 have perfect .fbx support by the moment not have .fbx support and the collada to .fbx conversion not work

If you wait time to time they have very greats offer and can buy the software for less money (200 less)
