To use the light painting tools, you must first select objects, and then select
a particular light painting tool: Pick Illumination, Add Illumination, or Remove
Illumination. The active button is highlighted in yellow, and when it is over
a selected object, the cursor changes to a crayon icon for the Add and Remove
Illumination tools, or to an eyedropper icon for Pick Illumination.
You can pick, add, or remove illumination through objects. For example, if
you select the floor as an object, you can work under the bookshelf, by working
through it. Once in light painting mode, you can’t select another object unless
you cancel the operation.
Interface
Intensity Specifies the intensity of the illumination in lux or candelas
depending on the units you have selected in the Customize >
Units Setup
dialog
on page 7601 .
Pressure Specifies the percentage of the sampled energy to be used when
you add or remove illumination.
Add Illumination Adds illumination starting at the vertex of a selected
object. 3ds Max adds illumination based on the amount in the Pressure spinner.
The pressure amount corresponds to a percentage of the sampled energy. For
example, if a wall has about 2,000 lux on it, Add Illumination adds 200 lux
to the surface of the selected object.
Remove Illumination Removes illumination starting at the vertex of a
selected object. 3ds Max removes illumination based on the amount in the
Pressure spinner. The pressure amount corresponds to a percentage of the
sampled energy. For example, if a wall has about 2,000 lux on it, Remove
Illumination removes 200 lux from the surface of the selected object.
