How it works...
• From step 1 to step 11, we built the basic shader of the leaf, using an al-
pha channeled image to "cut-out" the leaf shape on the plane and a gray-
scale image to drive the translucency effect.
• From step 12 to step 15, we added the color of the leaf, using it also with
a hue and intensity variation for the translucency effect. Then, we added
the bump, keeping the amount very low.
There's more...
Now, assign the same material to both the
leaf_generic_low
and
leaf_generic_hi
meshes on the eleventh layer.
The modeled leaf mesh doesn't need the alpha channel. So, select the
leaf_generic_hi
object and in the header of the
Node Editor
window, click on the
user data number to make it single user. Rename the new material as simply
leaf
and delete the
MASK
and
Transparent BSDF
nodes. Press
Alt
+
D
to remove the
Mix Shader Cutout
node from the link and delete it as well.
