Provides the current frame number of the current Render State. Usually this is simply the current frame number, but in future there may be shaders which modify this on the fly for special effects or new renderer capabilities to allow sub-frame values.
The Input connection is not used by this node.
A single object or device in the node network which generates or modifies data and may accept input data or create output data or both, depending on its function. Nodes usually have their own settings which control the data they create or how they modify data passing through them. Nodes are connected together in a network to perform work in a network-based user interface. In Terragen 2 nodes are connected together to describe a scene.
