The Anima Crowd tool gives you access to a wide variety of human character assets for crowd simulations, spanning from ambient to posing to walking. The crowd simulation consists of three components: an anima crowd object, an anima crowd path object, and anima character assets (actors). The components can be found in the Objects left-hand side panel tab, while their parameters are accessible from the Details right-hand side panel tab.

It is recommended to keep the usage of 4D assets to a minimum in your scene as they affect Chaos Envision's performance

Pick Path – Selects an exiting path (a spline object) onto which actors (human characters) can be added.

Create Path – Initiates a spline object creation. Click in the viewport and drag to create the first segment of your spline. Repeat as many time as needed, and click Done. The created spline is located in the Objects tab > Splines filter tab and is named AnimaCrowdPath by default.

Select Path – Opens the spline object's parameters in the Details tab.

Generate – Generates a crowd of people. The character placement on the spline is random. By default only downloaded rigged models are used, unless specified otherwise.

Drop actors for the crowd – A field where you can drop actors (human characters) from the Cosmos Library available in the Cosmos Browser and the Cosmos tab. The characters are used to populate the path when generating crowds. If no actors are dropped here, only downloaded rigged models are used by default.

Actor count – Sets a limit for the human characters when the Generate option is used.

Visible – Toggles the visibility of the actor on and off. Invisible actors are not rendered.

Position – Moves the actor along the X, Y and Z axes.

Rotation – Rotates the actor along the X, Y and Z axes.

Scale – Scales the actor along the X, Y, and Z axes.

Actor Properties – Shows properties of the selected actor, such as name. The properties cannot be modified.

Color Variation – Specifies a color variant for the actor from predefined presets.

Motion phase (%) – 

Speed (m/s) – Specifies the movement speed of the actor. Lower values make the actor appear more static, while higher values make the actor run.

Forward/backward offset (%) – Adjusts the actor's position along the path, moving it forward or backward. Positive values move the actor forward, negative values move the actor backward.

Slide offset (%) – Adjusts the actor's position along the path, moving it left or right.

Invert direction – Shifts the direction of movement of the actor.
