1 - THE MOON DIALOG BOX |
|
Select
Sky & Fog.Click on the Sky Options inverted triangle and
select Custom Sky. Change the sky colour to black. Drag over
the Haze picture and reduce the value to zero.
Figure 1
The last two operations ensure that a starfield will render
and not disappear when antialiasing.

2 - THE SUN & MOON DIALOG BOX |
|
Double
click on the Sun trackball to bring up the Environmental Attributes
dialogue box. See Figure 2.
Figure 2
Enter the three numbers shown for Numeric Sun Values, X,Y
and Z. Be sure not to miss the negative signs. Also check
Horizon Illusion, Use Moon Image and Starfield. Exit the dialogue
box.
If you render now you will see a large moon above the horizon
and a starfield surrounding it.

Use
the values shown in Figure 3 and values in between to position
your moon in the sky.

4 - ADDING TO THE SCENE |
|
Add
a terrain, a water material to the ground plane, a cloud plane
(NOT a sky preset), and a large sphere with a volumetric cloud
material applied and you get something like Figure 4. The
cloud plane, placed high up will allow the stars to shine
through. I always use spheres for volumetric clouds rather
than those infinite slabs, the rendering time is reduced dramatically.

| STEP
5 - EXPERIMENT WITH THE RESULTS |
|
In
Figure 5 you can see the cloud plane and large sphere in wireframe.
Figure 5
Experiment with the size of the moon (intensity value) and
the phase which is changed by checking Moon Phase and dragging
over the moon image, there are those rings of ice crystals
to play with as well.
You can also position the sun in the same way - just omit
the negative signs.
