Defines how the lower leg's roll/twisting is distributed between the knee and ankle.
When the lower leg needs to twist or roll based on IK, lowerLegTwist (a weighted range of 0..1) determines how much rotation is applied to the knee and ankle. When lowerLegTwist is set to 0, the twist applies entirely to the knee. When set to 1, the twist applies entirely to the ankle. The default value of 0.5 evenly distributes the twist between both the knee and the ankle.
