Moon and Stars These operations were carried out on the PC Windows version of Bryce 3D. See the note below for positioning in later versions. .
	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 The last two operations ensure that a starfield will render and not disappear when antialiasing.
	Double click on the Sun trackball to bring up the Environmental Attributes dialogue box. Enter the three numbers shown for 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 above and values in between to position your moon in the sky. If you have Bryce 3.1 there is an easier way to position the Moon and the Sun. While in Wireframe mode hold down Ctrl-Alt and double click on the sun's trackball. Then while holding down Ctrl-Alt, click anywhere in your scene to position the sun, and Ctrl-Alt-Shift toposition the moon - an Asterisk will appear to show the chosen position.
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 this. 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.
Here you can see the cloud plane and large sphere in wireframe. 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. Note In later versions of Bryce there is a much easier way to position the Sun or the Moon. In Wireframe view click on Sky & Fog so the Sun Trackball is visible. Hold down the Ctrl and Alt keys and double click on the Trackball. Now hold down the Ctrl and Alt keys and Left Click in your scene, an asterisk will appear, this is your Sun Position. To position the Moon in the same way hold down Ctrl, Alt and Shift and Left Click in your scene. Have fun!
