Some generators like Textures Output, Blend, Split, Combine, Rarefy and others have layers interface. Usually layers store similar parameters.
To create a new layer press the Add button with plus sign:
Note that some generators like Textures Output or Rarefy don't have any layers added by default. So keep in mind that if you see the Add button with the plus sign then you can add layers with additional properties here:
To change the layer order click and drag on it's name or any other non-active area:
Non-active area is any place within the layer except
To remove the layer drag it to the Remove field. When the layer is about to be removed the Remove field will be highlighted red:
Note that the Remove field is drawn over the layer itself. It was made intentionally - otherwise Remove won't be visible when dragging the layer atop of it.
Most of the layers have the additional parameters that could be rolled out by pressing the triangle chevron:
Note that for most of the generators only one layer could be rolled out. It was made to prevent excessive expanding node interface and cluttering of the graph.
Clicking on a pencil mark will allow to edit the layer name.
I'd like recommend to give reasonable names you your layers since it will help a lot to organize your graph. Since only one layer could be expanded it could be very hard to say what's this layer is about if it is just named "Layer 5".
