Houdini 18.5 Nodes Dynamics nodes

Agent Look At 2.0 dynamics node

Defines a target that an agent can turn its head to look at.

Since 14.5

This node is used in conjunction with Agent Look At Apply to select a target and adjust the transform of the agent’s head bone to look towards the target’s position. When using the Crowd Solver, the Enable Look At parameter should be enabled.

To define multiple targets, several Agent Look At nodes can be chained together. For more procedural setups, setting Target Type to Points allows each point in the specified geometry to be considered as a target.

Parameters

Group

The group of agents to modify.

Guide

Specifies whether guide geometry for the look at targets should be displayed.

Target Type

Specifies how the target’s position is determined.

Position

Uses the target position specified by the Position parameter.

Object

Computes the target position using the transform of the object specified by the Object path. If the object contains geometry, the centroid of the geometry is also included.

Points

Selects a point to look at from the specified geometry.

Agents

Selects a nearby agent to look at.

Object

Specifies the path to an object or SOP geometry.

Position

A world-space position for the look at target.

Neighbor Distance

Specifies the maximum distance when searching for nearby agents.

Max Neighbors

The maximum number of nearest neighbors to consider when selecting an agent to look at.

Search Distance

Specifies the maximum distance when searching a point cloud for nearby points.

Max Search Points

The maximum number of nearby points to consider when selecting a point to look at.

Horizontal Limit Angle

The maximum angle (in degrees) that the head can rotate horizontally to look at the target.

Vertical Limit Angle

The maximum angle (in degrees) that the head can rotate vertically to look at the target.
