Have you tried using a pin constrain it creates a shape that you can parent under any hierarchy in maya .
I roughed out a deer in this video, made a pin constraint and parented that pin under a lion head… you can constrain or parent, you’re preference
I have translated the solver over to see the input and result side by side - this does not effect the simulation backing back to the rig
Making SOME small progress and having heaps of fun.
Can I increase the radius of the deer’s torso to help with the legs collision but without changing the weight? when i increase the radius, my deer falls to the floor like a big, yet heavy water balloon
Can I make limit the legs rotation so they’re anatomically correct?
Did you find the reason for this? I suspect the problem occurs during recording, when the hip is constrained to the simulation. If the spine is a child of some other, more complex controller with space switches and maybe a SplineIK solver, then it may spit out a number of cycle warnings along the way.
Since I can’t reproduce your problem here, I can’t say for sure, but there’s a newer option that sometimes has an effect on cycles called Closed Loop Recording, try this.
Using the Extract Simulation command that Jason mentioned is a good way to spot this. It will run through the Record Simulation command, up until constraining it to the simulation, but before actually baking the keys. It’ll give you a chance to see what’s going on.
Normally, if every shape matches the character, you should be getting the most natural result.
Sometimes however, you do need more control and then you can either:
Nudge the Density
Take complete control with Mass
Density computes the mass based on the shape. If you don’t want that, you can set Density = Off which will expose the manual Mass attribute. You can see the final computed value of Density in the Manipulator for that shape.
