I think I’ve probably retargeted something in an IK leg incorrectly, but it’s a quadruped and only seems to be happening on the hind legs even though both sets of legs are set up the same way.
The hind leg feet easily separate from the lower leg, and there’s a ghosted capsule as well which I’m not sure what that’s indicating and a clue to why the foots disconnecting from the rest of the body.
Any thoughts much appreciated:
When you make a Pin or Attach Constraint, you’ll get this outline representing the target location for the Marker you constrained.
In this case, it looks like the feet are not connected to the lower leg, I’d have a look at the Draw Hierarchy attribute on the solver, it’s under the Display tab of the Attribute Editor. Maybe the feet was not Assign and Connected to begin with, and an Attach Constraint was used to glue them together?
You can use Ragdoll → Edit → Reparent to make the feet children of the lower leg as I’d imagine they should.
Thanks for the insight, yea it’s parented (even though the Reassign editor doesn’t show that hierarchy between them Draw Hierarchy shows a connection), but it’s still able to fly away during sim.
Setting the IK feet control marker to Translate locked seems to fix it instead of being Soft - in my mind Locked meant (doesn’t sim) and since its a marker for an IK control I’d want translate to not be locked? I think it’s a semantics confusion for me maybe.
To Ragdoll, everything is FK.
Both translate and rotate is local to its parent, similar to a Maya FK hierarchy. Despite your rig having IK controls, Ragdoll is given the final worldspace positions of each control and doesn’t know anything about IK itself.
About limbs flying off, it’s hard to say without a video. Maybe things are moving very fast, and the soft translation isn’t stiff enough? Maybe there are self-collisions, preventing the foot from staying in place?
Some debug tips.
