In the axe handle texturing exercise, you grouped the 3dplacement node for the wood grain
to the handle of the axe to make the texture stick to the handle. But you can also
bake
the
texture onto the axe handle by converting the texture projection to a file node. By baking
the texture node, you convert the 3dplacement node into an image file that is then mapped
to the color channel of the material, discarding the projection node, so you needn't group it
with the handle as you did earlier.
Follow these steps to bake the wood-grain texture to the axe:

Delete Unused Nodes and try again. The shader rebuilds itself to create a texture
file, a material, and a shading group
node that is automatically assigned
to the selected geometry. Delete
all unused nodes again to clean up
the Hypershade window. Your new
Shader network should appear as
pictured here.

Notice that the 3dplacement node, as
well as the Hypershade view, is removed
from the scene. Your axe handle's texture
now sticks to the handle as a mapped-file
texture instead.
