The final interface of the BasicShader node group
How it works...
I think you get the picture. Basically, almost any input or output socket of the nodes wrapped
inside a group can be connected to the outside of the node group to be tweaked.
The good thing about a node group is that you can make instances of that node (by pressing
Shift
+
D
). Note that when you modify the inner structure of a node group, the modifications
get reflected in all the group instances, but the outer (exposed) values on the node group
interface are local for each instance and can be individually tweaked.
Every newly created node group is available in both the Add menu (press
Shift
+
A
) and in
the slots in the Material window of the Properties panel, under the item Group, to be
added on the fly to the network.
To remove a node group, select it and press
Alt
+
G
. This will break the node envelope but
keep the content intact and still connected.
