Creating
an
ocean
material
using
procedural textures
In this recipe, we will build an ocean surface material, using the
Ocean
modifier and
procedural textures to create the foam and establish a set of nodes to locate it on the
higher parts of the waves, as shown here:
Getting ready
Before we start with the shader's creation, let's prepare the ocean scene:
1. Start Blender and switch to the Cycles rendering engine. Select the cube
and delete it (press
X
).
2. Add a plane (have your mouse in the 3D window and press
Shift
+
A
and
go to
Mesh
|
Plane
). In the
Object
mode, scale it to
0.300
. Don't apply
size.
3. Go to the
Object Modifiers
window and assign an
Ocean
modifier. Set
these values:
Geometry
to
Generate
,
Repeat X
and
Repeat Y
to
4
,
Spa-
tial Size
to
20
, and
Resolution
to
12
.
4. Press
N
and in the
Transform
panel set these values for the plane's
Loca-
tion
:
X -6.90000
,
Y -7.00000
,
Z 0.00000
.
5. Be sure to be at frame
1
and place the mouse in the modifier's
Time
slot,
press
I
to add a key for the animation. Go at frame
25
, change the
Time
value from
1.00
to
2.00
and press
I
again to set a second key.
6. In the
Screen lay-out
button at the top, switch from
Default
to
Animation
.
In the
Graph Editor
window, press
T
and go to
Linear
and press
Shift
+
E
to go to
Linear Extrapolation
to make the ocean animation constant and
continuous.
7. Rename the plane as
Ocean_surface
.
