Walk Inverse Kinematics makes feet stay on the floor, even when walking along uneven terrain.

Sets the minimum distance of the waist to the ground.<br>

This minimum distance is usually only used for crawling creatures

like the trite. If not required do NOT use the key/value pair or

set it to zero to save CPU.</td>

distance above the ankles.</td>

A square of the given size is used to find the height of the floor

below a foot. If set to zero a single point is used which is

considerably cheaper and used for instance for the trite.</td>

The vector from the ik_knee joint to the ik_dir joint specifies

the direction the walk IK will bend knee.
