Using Lights
The main differences between the 2D and 3D environment are lights and the Z axis. Lights are very important within the 3D environ-
ment as they are necessary to display 3D objects properly. There are three default lights in Compix Persona which can be maniplu-
ated freely.
The default lights are positioned
as shown to the right. Lights have
their own position values just like
any other object. By unlocking the
lights on the timeline, each position
becomes viewable as coordinates
(X, Y, and Z value).
Position of Lights
If defualt Light 1 were to be deleted,
the face of the 3D object to the
right becomes dark, as Light 1 was
illuminating from front. Default Light
2 is positioned slightly toward the
front, which is why the object’s face
can still be seen in detail. If Light 2
were deleted, the entire face would
go black. Default Light 3 is behind
the object, which allows us to see a
small portion of the object’s outline.
If Light 3 is deleted, and since there
are no other light objects in the en-
vironment, the 3D object becomes
entirely black.
