Toe controlled rig

Toe controlled rig

This script is a modified version of the rig_bipped_simple script. This rig allows you to control the foot IK with bones located at the position of the toe bone.

Why this rig:
1, Models that have "triple leg bones," such as a werewolf model, can be viewed as a human on tiptoes. With the default IK rig, it will be hard to control the paw/hoof of monsters walking on their "hind legs," as the paw will have a lot of floating/sinking in the ground if you don't carefully edit your keyframes.
2, If you want to film a close-up shot of the foot, like a moon-walk animation, and you want the toe to slide on the floor consistently without keeping the rotation of foot IK stationary or having lots of keyframes, then this script may come in handy.

In short, this is not a rig that you will use 24/7 but will come in handy in some specific situations/shots.

Please note that this rig will hide the foot IK so you will have difficulty in animating rotations of the foot pivoted at the ankle.

How to use this rig:
1, load your model and apply the rig_biped_toe, which should be in your rig menu, next to your rig_biped simple.
2, apply this rig. Your model should look like a model with the rig_biped_simple, but no foot IK. Instead, in the RigLegs group, you can see rig_toeFootL/R, and rig_toeRootL/R
3, the rig_toeFoot bones are there to control the rotation of the foot IK, and the rig_toeRoot is the parent of toeFoot and toe that controls the whole foot like what you would normally do with your foot IK.

Known issues:
Do not move, only rotate, rig_toeFoot. Unless you want to adjust the details of the positioning, otherwise the foot will get torn.

If you overextend the foot IK like extending the toeRoot bone beyond the length of the foot, then the foot will also get torn.

The bone is structured like this, "-->" = "is the parent of".
rig_root --> rig_toeRoot
rig_toeRoot --> rig_toe_Foot -->Foot IK
rig_toeRoot --> rig_toe
