World Layer

A world layer is a world object that performs a background node loading, starting at the specified distance.

Creating a World Layer#

To create a world layer via UnigineEditor:

On the Menu bar, choose Create -> Optimization -> World Layer

Layer Creation
In the file dialog window that opens, choose a node to be loaded and click Ok.

A Path to the Node
Place the node in the scene.

In the Node tab of the Parameters window, you can adjust the following parameters of the world layer:

Node tab of the World Layer node

A set of bounding box parameters:

Edit Size	Toggles the editing mode for the world layer node on and off. When enabled, the bounding box sides that can be resized are highlighted with the colored rectangles. To change the size of a side, drag the corresponding rectangle.
Point	A flag indicating if the distance to the object is counted from the center of the bounding box (if disabled, the distance will be counted from its nearest edge).
Size	The size of the layer's bounding box along the X, Y, and Z axes, in units.
Offset	The offset of the layer's bounding box along the X, Y, and Z axes, in units.

Loading and clear distances:

Load Distance	The distance from the object's center or edge to the camera, starting at which the node is loaded, in units.
Clear Distance	The distance from the object's center or edge to the camera, starting at which the node is not loaded, in units.

Layer parameters:

Name	The world layer .node file.
Group	The priority group value. Greater priority means faster loading.
Weight	The node weight value. Greater weight means faster loading inside the same priority group.

Editing and preview of nodes of WorldLayer:

Create	Bake the edited nodes into one WorldLayer. The button is enabled only when the Expand button has been pressed.
Expand	Unbake nodes of WorldLayer. This option is useful when you need to edit or reposition nodes of WorldLayer: they will appear in the nodes hierarchy list as child nodes of the WorldLayer node. Notice Do not forget to press Create to apply changes.
