Visibility

Alters the visibility of instanced objects.

Visibility Node

Random Strength: Sets the number of objects to randomly turn invisible.
Step Strength: Turns the objects invisible one at a time. By default, this is done in the order of their IDs.
Filter on: Corresponding object IDs will remain visible, no matter the other values. You may enter individual object IDs (i.e. 1, 3, 5) or number ranges (i.e. 2-6).
Filter off: Corresponding object IDs will remain invisible, no matter the other values. You may enter individual object IDs (i.e. 1, 3, 5) or number ranges (i.e. 2-6).
Invert: Reverses the order in which objects are made invisible.
Random Seed: Alters the randomization for Random Strength.

Enable Frustrum Filtering: Makes points visible/invisible based on a specific camera's frustrum.
Use Film Gate: Makes points outside the specified camera's Film Gate invisible.
Frustrum Border: Adds a border around the frustrum to include in filtering.
Camera: Determines which camera's frustrum to use. You can middle-drag a camera into this field or right-click to connect the selected camera. If a camera is already connected, you can also right-click to remove or show it in the Outliner.

Strength Map: Determines the input file (2D texture, animated texture, etc) that controls the shape of the invisibility effect.
Map Projection Axis: Determines the axis along which the Strength Map is projected.
Map Helper: Displays the object being used to interactively place the Strength Map in the scene. You can right-click the field to create a new helper object (a plane) if none exists. You can also middle-drag a mesh into this field or right-click to connect a selected mesh. If a mesh is already connected, you can also right-click to break its connection or show it in the Outliner.
Note: For the best results, assign the same texture to both the Strength Map and the Map Helper (this automatically happens when creating a new helper object).
