Understanding the Node Graph
The Node Graph is an editor which allows you to use Nodes that are linked together to create Vector Fields.
For instance, if you wanted to make a vector field that pulls particles towards a point, you could use a fade node with its fade type set to be a point. You then change its strength to be Min: -1 and Max: -.5 to orient all of the vectors towards this point. This could be considered 'Point Attraction' due to the particles being pulled towards a singular point in space.
The result of the above settings: Point Attraction
All commands below are performed in the Node Graph Tab. For instance, to show the Node Menu you need to Right-Click inside of the Node Graphs blank space (not on a node) for the menu to appear.
Here is an example vector field graph in the Node Graph.

|---|---|---|
| Open Node Menu | Right-Click |  |
| Spawn Node From Node Menu | Highlight + Left-Click |  |

| Delete A Node | Select Nodes Then Press DELETE Key or Right-Click the Node and select 'Delete' from the Menu |  |
| Select A Node | Left-Click |  |
| Add A Node To Your Selection | Ctrl + Left-Click |  |
| Box Selection | Left-Click in blank space and drag the selection box over the nodes you want to select |  |
| Add To Box Selection | Ctrl + Left-Click in blank space and drag the selection box over the nodes you want to select |  |
| Pan Node Graph Camera | Middle Mouse Button and drag -OR- Shift + Left-Click and drag |  |
| Zoom In/Out Node Graph Camera | Scroll Wheel Up/Down |  |
| Move A Node | Left-Click on Node and drag. All selected nodes will move. |  |
| Preview A Node/Graph In 3d Preview Window | Double Left-Click The Node. You will then see that the previewed node has a light blue outline around it, signifying that it is the node being shown in the viewport. This previewed node is also what will be exported when you choose to export nodes. |  |
| Edit A Nodes Properties | When Using Left-Click to select a node you can see the editable properties of the node in the 'Node Info' Tab. |  |
Nodes can be spawned from the Node Menu as well as from the shortcuts listed below.
