Directional Light [3DL]
The DirectionalLight node
Directional Light Node Introduction
A directional light is a light with a clear direction but without a clear source or distance, similar
to sunlight. This light shows an onscreen control, but the position of the control has no meaning.
The rotation of the control is used to determine from where in the scene the light appears to
be coming.
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 Directional 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 Directional 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.
