Creating tree shaders - the leaves
In this second tree recipe we will create the leaves shaders, as shown here:
Getting ready
Carrying on with the blend of the previous recipe, now press
Shift
and activate the
second and the eleventh layers also and select the
leaf_generic_mid
object.
How to do it...
Let's go straight to creating the leaves shader:
1. Click on the
New
button in the
Node Editor
window's header or in the
Ma-
terial
window and rename the material as
leaf_alpha
.
2. In the
Material
window switch, the
Diffuse BSDF
shader with a
Mix
Shader
node and rename it as
Mix Shader Cutout
. In the first
Shader
slot, select a
Transparent BSDF
shader node and in the second one,
a new
Mix Shader
node that will be renamed as
Mix Shader Add
Translucency
.
3. Add an
Image Texture
node (press
Shift
+
A
and go to
Texture
|
Image
Texture
), rename it as
MASK
, and connect its
Alpha
output to the
Fac
input
socket of the
Mix Shader Cutout
node.
4. Click on the
Open
button of the
Image Texture
node, browse to the
tex-
tures
folder, and load the
leaf_generic_mask.png
image (which ac-
tually is a simple black silhouette of a leaf, with a transparent alpha chan-
nel). Set the
Color Space
to
Non-Color Data
.
