On page 199 of Michael Duggan's book '3D Gamestudio', reference is made to the fact that, "There are... plug-ins you can download to import Caligari TrueSpace...".
I want to import a TrueSpace scene into GameStudio and am struggling to find the plug-in. Currently I can save a TrueSpace animation to various formats but then struggle to use append frames to capture all the key frames in the Med.
I'm not sure that this is the proper section of the forum, but I'll let your post live here Anyway, better try to export from Truespace into a format that (let's say) Milkshape can open; you've got straight export to mdl from there.
