FYI. None of these restrictions apply when your using ventilators plug in. I can set up blendshapes,constraints,clips, whatever because its all vertex export.

The limitation with ventilators plugin is that you cannot reuse the bones in gs because no rig information gets exported. But maybe you can add a bone structure to the model after it gets to .mdl, I have never cared about animation within med.

Thanks for the cm-quants information though. I never knew that
