F In steps 36 and 37, we built a last bump effect to add the sand grain if necessary, for

bump effects, to be driven by the last Math node value.
Every stage has been framed and properly labeled to make it more easily readable in the
Node Editor window.

One more thing we can do to improve this material is combine everything into a handy group
node, at the same time leaving the fundamental values to be tweaked exposed on the node
group interface. To do this follow these steps:
1.
Put the mouse cursor in the Node Editor window and press the B key. Two horizontal
and a vertical lines appear at the location of the mouse cursor. Click and drag the
mouse to encompass the framed nodes, leaving outside only the Texture Coordinate
node, the Mapping node, and the Material Output nodes. After the mouse button is
released, everything you encompassed is selected.
2.
Press Ctrl + G and create the group. Then press N in the Node Editor window to call
the Properties panel on the right side.
