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.

Node Editing and Preview

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.
