NEW in 3ds Max 2014: The pop Core Interface exposes the properties and methods related to the creation of Populate flows.

Properties:

    pop.DisplayType : enum : Read|Write
    DisplayType enums: {#StickFigure|#Segmented|#CrowdCustom|#CrowdSkin|#HighSkin}

Get/set the Display Type of the characters.

Default is #CrowdSkin

    pop.NumFrames : integer : Read|Write

Get/set the number of frames to simulate.

Default is 300.

    pop.RealWorldScale : float : Read|Write

Get/set the World scale relatively to the current System Units settings.

Default is 1.0.

Methods:

    <bool>pop.AddIdleArea <node>IdleArea

Adds the specified IdleAreaObj object to the flow simulation.

    <bool>pop.AddFlow <node>Flow

Adds the specified Flow object to the flow simulation.

    <void>pop.Simulate()

Simulates the flow using the current settings. Equivalent to pressing the Simulate icon in the Populate > Simulation panel of the UI.

    <void>pop.RegenerateSelected()

Regenerates the selected characters. Equivalent to pressing the Regenerate Selected icon in the Populate > Simulation panel of the UI.

    <void>pop.DisplayEnv <boolean>show

When the argument is True, the Environment objects (Flows, IdleAreas) will be displayed.

When the argument is False, the Environment objects will be hidden.

Corresponds to the Show Environment toggle icon in the Populate > Display panel of the UI.

    <void>pop.DisplayPeople <boolean>show

When the argument is True, the characters will be displayed.

When the argument is False, the characters objects will be hidden.
