Gen3Rig

Convert a Rigify Rig to a Ragdoll

The UI will show up in the properties panel in the 3D view window. Use the "n" key to toggle the side panel, and scroll to the bottom.

Instructions for Rigify

• First, you must create a rigify rig for your character
  • Shift+a -> Armature -> Human
  • Modify it and fit it to your character. Also set the weights. Automatic weights is the best method for me + manual tweaking
  • Use the rig's UI in the side panel ("n" key) to set all limbs as FK
• Make sure under template, select "Rigify (Pitchipoy)" and the mesh has an armature modifier pointing to the rigify rig
• Select only the mesh, then click "Generate Physpose Rig".
  • boxes are created which are really convex mesh (click display as shapes button to view the meshes)
  • Pin will pin one of the rigid bodies in place
• Make sure to create a "ground plane" rigid body object or your character will just "fall"
• Press alt+a (play) to start the simulation

Hints

• up the frame counter to 300000 (maximum) and also set Rigid Body Cache to 300000 end frame.
• up steps per second to 60, and solver iterations to 500 for best results (slow)
• click "draw as shapes" button to see concave mesh and debug weird collisions that make it unstable. Try moving things on different collision layers if its seriously messed up.
• When you start again at frame zero, sometimes the rigid bodies are out of whack
  • Select any rigid body / mesh / armature, and click "Reset to base pose" to fix

Instructions for Genesis 3

Genesis 3 is probably not working any more. Please use rigify

• Import the dae file exported from daz
  • The armature may not be scaled properly. Use edit mode to fix it's position (morphs that shrink seem to cause this)
• Select the armature and click "Convert Genesis 3 rig" in properties panel (at bottom but top of physpose tools)
  • An armature is created with shapes, and constraints, but all layers are hidden. Unhide all layers to see the full rig.
  • The "bone roll" on the legs is wrong for some reason sometimes. To fix, enter edit mode, select all leg bones and set roll to 0 degrees.

Notes about use on makehuman

Makehuman (old version, export full rig) is experimental. Select makehuman v1 to try.

A custom template

I used a custom template for my example video if you have seen it. The hair is also physics enabled (pony-tails).

Make a file in the root directory of this plugin, called custom_template.py. A function must be created that has the same name as the Armature object. Add contents such as this:

def PricessRig(poserig):
    # freedom of movement for the bone chain
    braid_dof = 65.0
    # build a chain of physbones. Start at "braid.R" which is the name of the bone.
    # Connect the chain root to bone "head"
    # Give the name of the mesh object to "shrink wrap" the rigid bodies so they can collide correctly
    # An Initial size of the bone, pre-shrink-wrap. Ensure its large enough to encapsulate the mesh
    # set dof
    # Density of the rigid body object.
    poserig.build_chain("braid.R", "head", "FTBraids-skinInstance.001", bone_size=0.1, bone_dof=(braid_dof, braid_dof, braid_dof), density=10)
    poserig.build_chain("braid.L", "head", "FTBraids-skinInstance.001", bone_size=0.1, bone_dof=(braid_dof, braid_dof, braid_dof), density=10)

    # Also I made jewlery dynamic
    # I used 2 bones instead of 1 for each jewlery piece. Limitation of this script at the moment.
    poserig.build_chain("bellyRing1", "abdomenLower", "MoonStoneBellyCharm_41324", bone_size=0.1, bone_dof=(180, 3, 180))
    poserig.build_chain("earring.R", "head", "REarring", bone_size=0.1, bone_dof=(braid_dof, braid_dof, braid_dof))
    poserig.build_chain("earring.L", "head", "LEarring", bone_size=0.1, bone_dof=(braid_dof, braid_dof, braid_dof))

    # This call is used to move things around on layers (so the earrings dont go crazy colliding with everything)
    poserig.move_physobj_collision_layer(['earring.R', 'earring.L', 'earring.R.001', 'earring.L.001'], layer_number=3)

def MyRig2(poserig):
    pass

#This line, PricessRig is the function name and ALSO the name of the armature object.

templates['PricessRig'] = PricessRig
templates['MyRig2'] = MyRig2
