■ Scope: Allows the scene graph nodes to form conceptual groups independent of the scene graph hierarchy. By default, all objects are visible to all cameras and lit by all light sources. The scope is an integer bitmask set to -1 by default. Background Every world object has two sub-objects: [Background] and [Active Camera]. The only parameter available for the Active Camera is selecting an active camera from sub-objects of the current World Object. Background parameters are listed below: ■ Approx.Object Size: Shows the object size with sub-objects. ■ User-defined ID: Displays the user ID for the object. ■ Image Mode X and Image Mode Y: Sets the background image repeat mode for the X and Y directions. Image mode can be set to either Border or Repeat. ■ Depth Clear Enabled: Enables or disables depth buffer clearing. If depth buffer clearing is enabled, the portion of the depth buffer that corresponds to the viewport is cleared to the maximum depth value. Set this parameter to True to enable depth buffer clearing. Set it to False to disable. ■ Color Clear Enabled: Enables or disables color buffer clearing. If color buffer clearing is enabled, the portion of the color buffer that corresponds to the viewport is cleared with the background image and/or the background color. Set this parameter to True to enable color buffer clearing. Set it to False to disable. Group Group is a scene graph node that stores an unordered set of nodes as its children. A Group object is represented as in the JSR-184 scene tree. NOTE Since most JSR-184 objects cannot contain any sub-objects, the JSR-184 exporter uses the Group object to represent the 3ds Max hierarchy. In this case, the Group object is assigned a name such as , where ObjectName is the name of the 3ds Max object with sub-objects. Parameters available for Group objects are the same as parameters for World objects. 7238 | Chapter 23 Managing Scenes and Projects
