15. Click on the Open button, browse to the textures folder, and load the leaf_
generic_bump.png image. Set Color Space to Non-Color Data and the Bump
node's Strength value to 0.200 , as shown in the following screenshot:
The leaf_alpha material network
How it works...
F From step 1 to 11, we built the basic shader of the leaf, using an image that has
alpha channel data to cut out the leaf shape on the Plane and a gray-scale image
to drive the translucency effect.
F From step 12 to 15, we added the color of the leaf, using it also with a hue and
intensity variation for the translucency color, and then we added the bump.
There's more...
Now, assign the same material to both the leaf_generic_low and leaf_generic_hi
meshes on the 11th layer.
The modeled leaf mesh doesn't need the alpha channel, so select the leaf_generic_hi
object, and in the toolbar of the Node Editor window, click on user data number to make
it single-user. Rename the new material as leaf and delete the MASK and Transparent
BSDF nodes, and then press Alt + D to remove the Mix Shader Cutout node from the link
and delete it as well.
