Creating a World Layer

To create a world layer, choose the Add World Layer option in the list of nodes in Editor panel. In the creation dialog window, specify initial parameters:

A Creation Window
Point A flag, indicating if the distance to the object is counted from the bounding box center (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.

After the initial parameters are set, click Ok and choose a node to be loaded in the opened dialog window:

A Path to the Node
Notice
You can skip the node selection process by simple clicking Ok. The node for the layer can be chosen anytime in the Layer tab.

Editing a World Layer

In the Layer tab you can adjust the following parameters of the world layer:

Bounding Box Parameters

A set of bounding box parameters:

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 Parameters

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

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.
