Hello I've recently started trying out 3D stuff, and I came up with a game idea where your mouse controls the direction one of you arms points in, so you can end up actually sword fighting. I then attempted to make ragdolls, and I saw on the forum that you could run some code to only simulate physics for certain bodyparts, like just arms or legs, but when I tried that, nothing was simulated at all. I'd like to only simulate the physics for the arms, and I don't know if you have to have the whole player as a ragdoll if you want that to happen, or make separate arm ragdolls for that to work. If anyone has any ideas, I'd really like to hear what I could do. Thanks to anyone suggesting!
My player is a ragdoll, and I only want to simulate physics for certain bodyparts at a time...

I think the tutorial will give you a starting point. The simulation can be applied to parts a setup, and this is mentioned near the end of the tutorial.
