1 activates the node. 0 deactivates the node.

The group of agents this node affects.

The source for the terrain object (SOP path or DOP object).

When Terrain Source is set to SOP, this is the path to the SOP.

When Terrain Source is set to DOP Data, this is the DOP object to use as the terrain geometry. This can also be specified as an object/data path for using specific geometry data that is attached to an object, for example, popobject/Geometry.

The primitives in the terrain geometry to use for ray intersections.

The direction of the terrain projection.

When Mode is set to Direction Vector, this is the direction of the terrain projection.

Specifies whether to cast a single ray from the agent’s point (Particle), or cast a ray from each of the agent’s legs (Foot).

When Sampling Method is set to Foot, projects the foot positions onto the plane defined by the agent’s position and the Direction vector before casting rays. This produces results that are consistent with the Particle sampling method if the agent is on flat terrain. If this option is turned off, the agent is lowered by the average distance of each foot from the terrain.

An additional offset that shifts all the agents up or down.

When turned on, projects the force point attribute onto the plane defined by the terrain normal.

When turned on, outputs the specified attribute, which indicates the normal of the terrain geometry underneath the agent.

When turned on, outputs the specified attribute, which indicates the primitive that the agent is projected onto in the terrain geometry.

When turned on, adds the specified attribute with the coordinates of where the agent is projected onto the terrain geometry.

When turned on, adds the specified attribute with the agent’s offset from the terrain (according to the Mode, Sampling Method, and Offset parameters). This can be used in combination with the primitive number and UV coordinates to stick agents onto deforming terrain geometry.
