A Distant light illuminates the scene from a particular direction, as if it were very far away. Its light rays are all parallel so it brightens all the objects in the scene from one direction.
One of the several available user lights in ICErender.
Distant Light Tip:
a.This has the same effect as the sun would have on a rendering - simulation the sun.
b.Best used by placing outside the model shining towards it.
c.Best used with only one distance light placed in the scene.
d.Works best with windows in the scene to be able to see the "sun".
