Next, make sure to select the objects that you want to export, and export them to .3DS *from* 3ds max frame by frame.

Import the frames one at a time in MED using "Append Frame...", make sure to clean everything up before using the model

Old and painfull workflow , even old engine Blitz3D have a complete exporter directly from 3DSMAX to it in some clicks!

Learn Blender and use Ventilator's plugin , lot more easier to export animations
