# Crowds
To render big crowds of people Depence has a so called MassCrowd Object, which procedurally places random instances of animated characters.
## Add new Mass-Crowd
In the library window, navigate to `Models > Peoples > Crowd` then select and drag a Crowd-Object into the Scene.
You can select the crowd over this gizmo icon.
{% hint style="info" %}
Note that this object is optimized to render thousands of instances, but having multiple MassCrowd objects in one scene can increase memory requirements and loading time a lot! Instead of using several objects, try to use empty - NoGo Areas.
{% endhint %}
## Empty - NoGo Areas
The Crowd instances are distributed depending on the current settings. The empty areas can be used to keep specific regions empty. This can be around stages or other scene elements.
### Create Empty regions
The crowd-object can use the axis-aligned bounding box of any object to cull out the instances.
#### Step by step
1. In the `3D-Hierachy window > Add > 3D-Object > Cube`
2. Place and size the cube to define the empty area\
\&#xNAN;*(note: the cube shall be in clash with the floor to be detected as NoGo area)*\
3. Select the Crowd Object and in its Settings click on "Empty Areas ..."
4. Drag the Cube object from the 3D-Hierarchy in the Dialog box\
5. Select the Cube again and set the Visible property to false\
6. After updating the Cube's transformation, click on Crowd settings "Refresh" button to refresh the empty area\
### Focus Object
The focus object allows you to define another object in the scene as a focus point, where all crowd instances will look at. The focus object can be any object type, f.e. a Generic > Group Object
{% hint style="info" %}
NOTE: The crowd focus doesn't update in realtime when the focus object is moved by keyframes.
{% endhint %}
