I'm trying to create a ragdoll to animate a falling person, following How To Make Any Rig Into a Rag Doll in Blender (Tutorial).
Basically, it means that you create a cube (rigid body) for each bone, and the connection between the bones is converted to an empty with a rigid body constraint that is set between every two cubes.
E.g. this is how my ragdoll looks like:
- It has a generic physics body constraint.
- There's a zero limit on the distance. This (I belive) means the two spine cubes cannot change distance from the empty - it should act as a hinge.
- There's a bit of freedom in changing the angle (between objects?) - represents the common back of a person (non contortionist).
Why is there such a big change from the 1st frame to the second?
Note: I also tried with no angular limits (thinking the limits are outside the initial rotation and might cause an abrupt change), but it didn't seem to help.
For completeness, here's the .blend file for this.
