Light Modifiers

From ZBrush Info

Light Color (color patch): Set by selecting a color with any of the color pickers and clicking on the color patch. You can also click and drag from the patch to the canvas to pick a color. Light color is visible on the preview sphere, but you must be in Best Render mode to see its effect in the scene.

Intensity: Sets the strength of the selected light. Range = 0 to 2.0.

Intensity Curve: The intensity curve controls the intensity fall-off from the center of the light to the edge of its effect.

Ambient: Sets the amount of non-directional global ambient light. Range = 0 to 100. Default = 3.
