Ambient Light [3AL]
The AmbientLight node
Ambient Light Node Introduction
An Ambient Light is a directionless light that globally illuminates a scene. It has no real position
or rotation, although an onscreen control appears in the viewer to indicate that a light is present
in the scene. Position controls for the viewer are provided to move the widget out of the way of
other geometry, if necessary.
Similar to a Camera 3D, you connect lights into a Merge 3D and view them in the scene by
viewing the Merge 3D node. Selecting a light node and loading it into the viewer does not
show anything.
Inputs
The Ambient Light node includes a single optional orange input for a 3D scene or 3D geometry.
–
SceneInput: The orange input is an optional input that accepts a 3D scene. If a
scene is provided, the Transform controls in this node apply to the entire scene
provided.
Basic Node Setup
The Ambient Light node is designed to be part of a larger 3D scene. You connect the light
directly into a Merge 3D. Separating lights into different Merge 3D nodes allows you to control
which lights affect which objects.
