Worlds Page
The Worlds Page is a tool page in the World Editor. It can be found under the Instance tab.
The list shown in the Worlds Page displays the instanced world resources that have been placed in the current world. When a world in the list is selected, clicking in an editor viewport places a new instance of that world in the current world. Placement adjustments are applied if they're enabled in the Placement Page. If multiple worlds are selected (by using shift-click or control-click), then one is chosen at random each time you click in a viewport.
The Instanced World tool in the upper-left corner of the Worlds Page places a blank instance in the world. A world resource can be assigned to it under the World tab in the Node Info window.
If the Place on instances box is checked, then new instances can be placed on surfaces belonging to other instances already in the world. If this is not checked, then other instances are ignored, and new instances are placed only on surfaces that are part of the main world.
Modifiers
Instanced worlds may have one or more modifiers attach to them. A modifier changes the instanced world in some way at the time it's loaded. After an instance has been placed in the world, modifiers can be added and edited under the Modifiers tab in the Node Info window. See Modifiers for information about the specific modifiers that are available.
The Worlds Page contains a list of modifier presets that can be used to automatically applied frequently used modifiers to instances as they're placed in a world. A modifier preset is created by selecting an existing instance in the world that already has modifiers attached to it and choosing New Modifier Preset from the popup menu in the Worlds Page. When a modifier preset is selected in the Worlds Page, its modifiers are copied to each new instance that is placed in a world.
