In a scene, there are unique anchors for the following elements: render layers, render passes, and cameras. Anchors identify these elements in the resulting Toxik composition that is created after importing a 3D scene.

One or more anchors can be associated with any node in a dependency graph. You can add, remove, and edit anchors. You can also view a node's list of anchors. When a node has an associated anchor, the anchor tab at the upper-left of the node turns blue.
