The following videos are presented by Senior 3D Software Developer Cameron White, who covers several updates to Agent Primitives that are new in Houdini 19. Cameron goes over how to create an agent, round-tripping between crowds and KineFX, writing sequences to disk, how to add things to your crowds (props, for example), Vellum sim with agents and specifying custom data to your agent definition for varying the look of your crowd sim.

Agent Primitives: Overview

This video provides an overview of agent primitives and the different parts that make up the agent definition. Additional topics include: creating agent primitives and rigs, round-tripping between crowds and KineFX, and efficiently caching crowd sequences to disk.

00:53 - Intro to agent primitives and agent definitions
11:54 - Creating agent primitives and rigs
23:08 - Caching agent definitions

Agent Primitives: Geometry

This video provides an in-depth look into agent shapes and layers, and discusses new features in Houdini 19 that simplify the workflow for producing geometry variations in a crowd.

00:01 - Intro to shapes, deformers, and layers
06:56 - Demo of Agent Layer 2.0 and Crowd Assign Layers
23:02 - Deformers and rigid shape bindings
27:25 - Bounding boxes
30:59 - Vellum workflow

Agent Primitives: Metadata

This video covers a new feature in Houdini 19 which allows custom data to be stored in the agent definition and shared between instances of an agent. A custom tool is developed to demonstrate how this feature can be used, and several new features in Houdini 19 related to dictionary attributes are also demonstrated.

00:01 - Intro
01:27 - Dictionary attributes and the Attribute Adjust Dictionary SOP
09:32 - Storing custom data in the agent definition
10:48 - Demo

    Hi, I have an issue that I cant find a solution for. When I apply a layer of clothing geo, it stays rigid and doesn't deform according to the agents' animations. Im trying to use FBX animations/skins for this.
