View source for Graph Editor

= Editing =
The graph editor is typically opened by right clicking on an asset in [[Content Manager]] and selecting "Open > Show in Graph Editor". This will open a graph editor window for the asset in question and load the "default.nodegraph" file from that asset. Like config files, the format of the node graph is common across [[:Category:Asset_KIND|Asset Kinds]], but the specific interpretation of the various components varies.

The graph editor window is divided horizontally into two panels; the left shows the graph itself and the right shows editable properties of the selected node(s). The divider can be dragged horizontally to vary the space available to each panel. The Graph (left) panel can be scrolled horizontally and vertically using scroll bars, scroll wheels, or by holding the space key and dragging.

== Nodes ==
Right-clicking on any empty space in the left panel shows a contextual menu which includes the ability to add a new Node. Various Node Types are available depending on the context in which the Graph Editor is operating. Some nodes are output-only; some have both inputs and outputs, and some are input-only. Typically, a graph starts with one or more output-only nodes, works through a number of in-out nodes, and ends in one or more input-only nodes. Each Node Type may have its own visualisation in the graph, although all nodes share some basic visual features.

Nodes may be selected by clicking on them. The selected node is shown with a colored border.

Nodes may be assigned a label. This is used for display purposes only and is not used by the logic processing in the graph. If not customised, a default label is applied based on the Node Type.

== Connectors ==
Node inputs and output connectors are visible on the outside edge of each node as small squares. Connections can be created between nodes by dragging from an Input connection to an Output connection on a different node (or vice versa). Adding a connection will remove any existing connection(s) from both connectors unless the option/alt key is held during the connection process.

== Properties ==
The selected node's properties are shown in the Properties (right) panel. The available properties are dependant on the Node Type. Different nodes offer different properties according to their function. Some nodes perform a fixed function on their inputs, whereas others are heavily customisable with large numbers of parameters. Any parameter changes take effect immediately.
