Muscle-Controlled Active Ragdolls (Dynamic Motion Synthesis)

Hello! I have been thinking about creating an Active Ragdoll which contains the realistic aspects found in active ragdolls within Euphoria Engine.

This is a demonstration video on Euphoria engine’s Active Ragdoll ^

From this showcase, I have learnt that NaturalMotion utilises Muscle components rather than hinges or in other words, motor6Ds for their ragdoll controller. This is quite interesting and in my own opinion actually beneficial.

After thinking for a bit, I have realised how much more realistic behaving a Muscle-Controlled Active Ragdoll would be compared to a vanilla Motor6D-controlled one, hence, I would like to request some help on brainstorming concepts or ideas on using Motor6Ds or bodymovers to suit as muscles for both a realistic player-controlled active ragdolls and NPC active ragdolls.
