Control (UI) Default Value Function
rotationOrder XYZ Sets the order in which rotation is applied:
• XYZ
• XZY
• YXZ
• YZX
• ZXY
• ZYX
interface: SRT Values
translate 0.0, 0.0, 0.0 Controls light translation on the xyz axes.
rotate 0.0, 0.0, 0.0 Controls light rotation on the xyz axes.
scale 1.0, 1.0, 1.0 Controls light scale on the xyz axes.
interface: Transform Matrix
matrix 1.0, 0.0, 0.0, 0.0, 0.0,
1.0, 1.0, 0.0, 0.0, 0.0,
0.0, 1.0, 1.0, 0.0, 0.0,
0.0, 0.0, 1.0
Controls transformations using a matrix in place of individual SRT
controls.
enable aim constraint disabled When enabled, specify aim constraint options.
enable aim constraint: enabled
targetPath none Specifies the object or objects to constrain to. If you want to aim
a light to point at a target, this would be the target. If you set
multiple targets, then the constraint aims at the average center
of the objects.
targetOrigin Object Sets how the center of the target object is calculated:
• Object - uses the local origin of the object as the target.
• Bounding Box - uses the center of the object’s bounding box
as the target.
• Face Center Average - uses the face center average of the
object as the target.
• Face Bounding Box - uses the face center average of the
object’s bounding box as the target.
