3. Click on the
Open
button and load the texture
spacehull_displ.exr
.
Go back to the
Object Modifiers
window and set the displacement
Strength
to
0.200
; in the
Texture Coordinates
slot select
UV
.
This way the displacement features get mixed with the hull panels of the shader, giv-
ing a nice result. The
spacehull_displ.exr
is a 32 bits float displacement map
baked in the Blender Internal engine (at the moment Cycles doesn't have the possib-
ility to bake textures or shaders). I modeled with planes and scaled cubes a simple
greeble panel, then I baked the displacement on a different and unwrapped plane:
If you want to have a look at the scene, open the file
1301OS_06_greeble.blend
.
One last thing we can do to improve the model is to assign to the
Torus
mesh, after
the
Displace
modifier, a
Decimate
modifier set to
Planar
with a ratio of
0.3000
or
similar; you will inevitably lose some detail but will obtain a lot lighter mesh.
