To open the Node Setup simply move your mouse over an empty cell in the Project Grid. Click the PLUS button to begin adding a new node to the Project.
For those of you who used ShaderMap 2 you may recognize this as a streamlined version of the, now removed, Map Setup page. Select a node to be added to
the project. You can read information about the node, including required inputs and a description of the node. Double click on a node in the list to add it to the
project. If the node requires inputs then care should be taken to add those nodes first, else a warning message will be displayed.
The nodes are sorted into 3 groups alphabetically. Source 3D Models, Source Maps, and Maps.
