Are there any unreal converters? any scripts to write .usx, .t3d?
Its a long shot but i gotta try!
Thanks
Ian
Milkshape3d is probably what you want. Its Shareware though, but it can import obj and 3ds files and export to unreal, quake 3, etc.
Aah… Well, I know for a fact that there are scripts that export to .obj and .3ds (though I don’t think that 3ds can manage UV maps yet…).
So, if you use your script to export to obj, open in Milkshake 3D, convert… and Bob’s your auntie’s live in friend!!!
