The Lamp Tool dialog box controls are similar to those of the Object and other Library Part dialog boxes.
See Object Tool Settings for a description of the common Settings panels.
Basic Light Parameters
All lights and lamps have certain parameters in common, on the Light Settings Panel of Lamp Tool Settings.
Some of these are described below, in this section:
General Light Sources and Effects
The General Light Sources folder contains light sources that serve to illuminate the project, and have many sophisticated optional effects. The effects are advanced-level settings that are separated from the basic parameters in the Settings dialog box.
These effects parameters are introduced below, in this section:
See General Light Sources and Effects.
The effects you set for your lamps and light sources are taken into consideration for Photorenderings. As a rule, the global effects are set in PhotoRendering Settings (turn on GI, Lens effect, Intensity). You can then fine-tune these in your individual lamp/light objects.
Note that certain individual Lamp parameter settings will take effect only if the corresponding global parameter in PhotoRendering Settings is switched on. These situations are noted in the descriptions of light effects, which follow.
