The light painting tools in this rollout al low you
to touch up shadowed and illuminated areas
manually. You can use these tools to touch up
shadow and light-leak art ifacts without having to
do additional remodeling or radiosity processing.
Using Pick Illumination, Add Illum ination, and
Remove Illumination, you can add or remove
illumination on one selection set a t a time.
To use the light painting tools, you must first sele ct
objects, and then select a particular light painting
tool: Pick Illumination, Add Illumination, or

highlighted in yellow, and when it is over a selected
object, the cursor changes to a cray on icon for
the Add and Remove Illumination tools, or to an
