Preview for New Nodes
When new Nodes are created, this global option defines if Nodes should be displayed with a preview thumbnail or without. The preview can, however, be hidden or displayed anytime at Node level.
Grid
Here you can define if a grid should be displayed in the Node Editor. The Nodes can then snap to the grid.
Navigator
Here you can define if you want to define globally if the Navigator should be visible in the Node Editor. This can, however, be switched temporarily in the Node Editor (menu: View/Show Navigator).
Info
This option can be used to display the Info Area at the bottom of the Node Editor in which you can, for example, display the data type of a selected port. Alternatively, the Info Area can be toggled on or off in the Node Editor's View menu.
Errors
If a Node produces errors or has been fed with invalid data types, it will be framed in red (look for error messages in the info area that can give you more information). This red frame can be hidden if you disable the Error option.
Here you can show or hide the display of IDs and Asset IDs in the Node Editor's Info Area. The Info option must also be enabled in order to display the IDs.
No Value
If the Heat Map is activated in the Node Editor's Debug menu, this color is used for Nodes that have no active connection to the rest of the setup or only execute a static calculation. The are, for example, Nodes that only need to be processed once and subsequently supply the setup with the same value.
Gradient
This color gradient is used for Nodes to highlight their portion of the overall calculation time when the Heat Map is activated in the Node Editor's Debug menu. Simple Nodes and those that calculate quickly will be assigned color values from the left end of the gradient. The color scheme is always relative to the calculation time of the current setup and is not an absolute indicator, e.g., for the time required. The colors are therefore more of an indicator for which Nodes within the setup are responsible for the lion's share of the calculation time. More about the options available and how to use the Heat Map can be found on the Overview page about the Node debugging tools.
