Models saved as .3ds from Model Converter X have no animation or smoothing as the.3ds format dosen't support them.
The .3ds format will still have the texture maping saved and moving parts will not be welded/attached to the neighboring part in game. (ailerons won't be welded to the wings .ect.) Note: Some really old models this may not be true for. You will have to name and animate all parts and things like that.
The .3ds format is stuck with the old 8.3 filename so you may need to do some guessing to get the right texture loaded right material in the Material Navigator. Model Converter X should keep the model's scale right so I'm not sure why FOO FIGHTER has huge model in game.
