Unigine::NodeReference Class

Header:#include <UnigineNodes.h>
Inherits:Node

A node reference is a node that refers to an external .node file on the disk, which is obtained by exporting a node from the world.

Notice
The world can contain several instances of node references referring to the same .node file.
The .node file usually contains a pre-fabricated node (or a hierarchy of nodes) with all the materials and properties libraries that are required for its rendering. All changes that are made for the node reference via UnigineEditor are saved into this file.

The node reference should be used instead of the node if there a lot of identical objects repeated in the world: it will enable to avoid manual editing each object if you need to make the same changes in all of these objects.

Unlike regular nodes, reference nodes are loaded into the world faster because of the internal cache usage.

Notice
A bounding box of the reference node is equal to the bounding box of its root node (child nodes are disregarded).
