is there a way to export all frames of a blender-file into a MDL file without typing in the frames manually?
no, but it would be easy to hack in such functionality.
...and in future versions i will maybe completely remove the need for manually defined animation sequences and make this based on blender actions.
Do you have a new link? "Page cannot be found"
...
by the way, if you are a blender user then you also might find this interesting:
