When turned on, prevents the ankle and toe from sliding when the foot should be planted. The channels specified on the Agent Prep SOP are used to determine when the foot should be planted during the animation clip, as well as how to blend out of the locked position. This option also improves terrain adaptation for situations where the unadjusted foot position is above the terrain, since the solver can distinguish between when the foot should be planted and when the foot is actually supposed to be above the ground. This option may still be used if no terrain object is specified.

The optional agentterrainadaptation_footdown float array point attribute can be used to override the foot down values computed from the agent’s animation clips. The attribute is expected to contain a replacement foot down value for each entry in the agentrig_footchannels point attribute. This may be useful when applying terrain adaptation to cached agents.

When turned on, adjusts the position of the hips to ensure that the legs are not over-stretched when planting the feet on uneven terrain.

Specifies an additional offset to shift the hips up or down.

When turned on, specifies how much the hips can be shifted by in a single frame. This can reduce sudden hip motion on uneven terrain.

When the distance from the upper leg to the target ankle position is greater than this percentage of the maximum leg length, the knee angle will be damped so that it smoothly approaches a 180 degree angle as the target ankle position is extended. This can prevent the knee from popping when the leg is almost fully extended.

When turned on, adjusts the agents' legs to conform to the terrain.

When navigating uneven terrain, the agent can lean forward or backward. When turned on, this parameter specifies the maximum angle (in degrees) that the agent can tilt in a single frame.

Specifies how far (in degrees) the agent can lean backward.

Specifies how far (in degrees) the agent can lean forward.

The original facing direction of the agent. This is used along with the Reference Up vector to define the plane of the 2-bone IK adjustment for the legs.

The original up vector of the agent. This controls the direction of hip adjustment and foot planting.

When turned on, displays guide geometry indicating the positions of the lower limb joints and whether the feet are locked.

Adjusts the size of the guide geometry.

Adjusts the Scale to indicate when the foot is locked.

Specifies the color of the guide geometry. When Enable Foot Locking is turned on, the color ramp indicates when the ankle and toe joints are locked or blending out of the locked position.
