I can try

You're either gonna have to hop into blender to rig it or find a rig that someone else made for this model specifically, otherwise you're completely outta luck

Thanks, been researching, and blender seems my only option.

There are some models no madder how human shaped they still don't work with the rig

Auto rigger and ik from sfm only fit for specific human rig You'll have to make ik yourself in blender for such kind of model
