After starting the InnerWorld plug in you see some button in the lower left corner. Right to the buttons is the area for the parameters of the selected node. When no node is selected this parameter area is empty. Above is space for constructing the graph calculating the terrain.

• Blue area: The button area.
• Orange area: The graph area, currently with four nodes. The node in the right side is selected.
• Green area: The parameter area of the selected node.
