Light Manager Dialog
Used to control light setups and the settings for both global and source lighting. Other options let you place or delete source lighting cells and to define the direction of North in the model. When you highlight a light source in the Light Name list, its settings are displayed for editing as required.
For some of the lights, the settings are provided in different tabs such as Details, Solar Position (only when solar light is selected), Volume Effects (only for Solar, Directional, Point and Spot Lights) and Expert.
For some light source settings such as Solar, Directional, Spot, and Area Lights, you can view the Light Preview. The preview is intended to give you a quick view of the light’s color and is especially useful for adjusting volumetric effect. The Light Preview is displayed at the bottom of the Light Manager dialog can be enlarged by double-clicking on it.
Depending on the type of light selected, you can choose from different light widgets. These light widgets are models that are stored in the Bentley_LightWidgets.dgnlib, which is located in ..\Default\Materials\ folder in MicroStation's program directory. You can create additional light preview widgets in another DGNLib file and add the location of that DGNLib file to the MS_MATERIAL configuration variable. The name of this DGNLib file must contain _LightWidget. A saved view must be created for each preview with a unique prefix name that identifies the object, separated with $$ and then a suffix that describes the light type. The suffix names are solarlgt, directlgt, spotlgt, pointlgt, and arealgt. For example: Room$$directlgt, Lamp$$pointlgt, Window$$directlgt, Office$$arealgt.
When creating light widgets each model should have a light setup with the name ‘Preview’ to indicate that this setup is to be used as a Light Preview widget.
