1 activates the node. 0 deactivates the node.

The group of agents that this node should affect.

Source for the terrain object (SOP path or DOP object).

The path to the SOP (when the terrain source is set to SOP).

The DOP object to use as the terrain geometry. This can also be specified as an object/data path for using specific geometry data attached to an object. For example, popobject/Geometry.

This parameter is only available when the terrain source is set to DOP Data.

The primitives in the terrain geometry to be used for ray intersections.

Controls the direction of the terrain projection.

Direction of the terrain projection when Mode is set to Direction Vector.

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 will be lowered by the average distance of each foot from the terrain.

Additional offset that will shift all the agents up or down.

When turned on, the force point attribute will be projected onto the plane defined by the terrain normal.

When turned on, an attribute will be output indicating the normal of the terrain geometry underneath the agent.

When turned on, an attribute will be output indicating the primitive that the agent was projected onto in the terrain geometry.

When turned on, an attribute will be added with the coordinates of where the agent was projected onto the terrain geometry.

When turned on, an attribute will be added 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.
