Spot Light [3SL]
The SpotLight node
Spot Light Node Introduction
A spotlight is a light that comes from a specific point and that has a clearly defined cone, with
falloff of the light to the edges. Experienced stage and theatre lighting technicians may
recognize the spotlight as being very similar to practical lights used in live productions. This is
the only type of light capable of casting shadows.
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 Spot 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 Spot 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.
