Just showing a Before and After rig I fixed XD If you want me to rig a model for you to animate smoothly/ act like a half life rag doll you can commission me for a low price of $5-10 for a standard rig, $15-20 for a rig that a bit more complex. $40-50 for realistic physics. This type of rif will take a while,

Commission payments can be done threw my paypal link: https://www.paypal.com/donate/?token=CekmnUjeXWlJst0cwd6GphaU01upHiUPncrn1zFCN0b0KtFSZJt_r3V0qpR8KZd4cFTAhW&fromUL=true&country.x=US&locale.x=en_US
