hello Jongwoo, I am working with powered soft exo skeletons in TU Darmstadt, germany. This is regarding your query on Compatibility of OpenSim Models with MuJoCo. I have to develop a complete lower limb model in MuJoCo, so it will be very helpful if I could import the opensim model to MuJoCo directly. Could you please advise me if you were successful in doing so. Thanking you, Regards, Akhil
