ok,ok MAX isn't free, but can blender export the animation so, that i have not too much work. e.i. click at an export-button in blender and import it easy in med.
yes. ventilator wrote a py script for blender that exports blend to mdl7 including bones. in blender 2.45,(latest version), you get an improved fbx exporter, fbx is supported by 3dgs as well. so choose between the two.
