There
are several ways to create universes and star backgrounds,
the following will show you a few ways to do so.
First you click on the ground plane and delete it from the
image. Then you click on the 'Sky & Fog' menu. Below the
Create Menu and Image you click on the little arrow and choose
Custom Sky. There you change the sky color from blue to black
by clicking and holding down the left mouse button, then choose
black.
Now you go to the 'Sky & Fog' menu options below and to
the right of the Sun Control and click on the little arrow
and then select the 'Edit Sky Fog' option. You are now in
the 'Environmental Attributes' window. Click on the Atmosphere
tab and set the Fog and Haze values all to 0 (zero). Click
on the check mark to keep the changes and return to the main
window. Now the sky is black without a horizon.
Now you create a cube from the Creation menu. Then you click
on the 'M' button attached to the cube. This will take you
to the Materials Lab, where you can choose the texture you
want as a space background.
I use [cosmic volume, supplied on the CD] most times when
making a universe image or an image that needs a space background.
Enter the Materials Lab and import the Cosmic Volume.mat file
into the category you want, in Bryce. You can also use Galaxy
Volume or Nebulae Volume, also on the CD.
|
|
When
you have imported the Cosmic Volume, choose it as the texture
for your cube. Click on the check mark and return to the main
image view. Now click on the 'A' button attached to the cube
and the 'Object Attribute' window pops up. Now change the
size (those in red) in the x, y and z fields from 20.48 to
2048, (just remove the decimal sign). This is to have the
same proportions of the cube when you make it larger.
Bryce is using it's own 'units' of measurements, and it is
easier to work with objects like spheres, cubes and stretched
cubes. You can use the basic size of 20.48 and calculate if
you want the cube a bit larger. I use 20.48+20.48/2=30.72
and so on. Now click the check mark and you will end up with
a cube with the size of 2048 x 2048 x 2048 in size. Your view
will now be almost in the center of this cube and since it
is a volume texture you are using, you are in the middle of
your little universe image with stars and gas clouds all around
you.
You may be satisfied with your image at this point. If you
are not, there are other ways to make a space image or a background.
|
|
Start
as you made the above image but choose a stretched cube instead.
Click on the 'A' for the attribute window and change only
the size for the y and z value y to 4096 and z to 2048, leave
the x value as it is. Now change the rotate value for the
y angle to 45°. Click on the check mark to get back to the
main view window and render your image.
Now you have an image of a nebulae cloud with some stars and
other smaller gas clouds. You can change it before you render
the image by moving the stretched cube, by using the arrow
keys on your keyboard and moving the cube further away from
you. Experiment and you will finally have a large universe
image with many different nebulae clouds and other gas clouds
and stars.

Now
to the easier way to make a space background, but one that
you can't change and experiment as with the above examples.
Click on the 'Sky & Fog' menu as mentioned earlier and
choose the custom sky option. Make the sky a black. Click
on the lower right arrow beneath the sun control and choose
the 'Edit Sky' option. Click on the Atmosphere tab and give
the haze value 0(zero). Then select the SkyLab, and select
the Sun & Moon tab. You will see more options, choose
the starfield and comets by clicking once on them and then
click on the check mark to get back to the main view window.
Render your image.
You can also add stratus or cumulus clouds from the SkyLab.
I often use cumulus clouds only since the stratus clouds very
easily block the view of the sky. You can also change the
amplitude and frequency of the cumulus clouds to 150-250.
Experiment with different settings to see what you find looks
best for your image.
|
|
Now
you know a great deal about making space images and space
backgrounds. But there are more things you can do to make
a more complex space scene. You can copy and paste the cube
and move it further back into the image. You will see the
effect enhances the image and it's complexity.

STEP
6 - ADVANCED OPTIONS |
|
To
make it more advanced, change the colors of the texture itself.
Click on the 'M' button attached to the cube, sphere or stretched
cube and the Material Lab window. Make sure the 'Procedural
Texture' is marked and click on the round button to enter
the 'Texture Source Editor'.
|
|
In
the 'Deep Texture Editor' you can see the colors used for
the Cosmic Volume. Click on the colored buttons in the 'Deep
Texture Editor' and hold down the left mouse button to get
a color scheme and choose the color you want to use in the
texture. When you are finished with your choice of colors,
click on the lower right check mark to go back to the main
view window.
|
|
If
you are satisfied with your choice of colors you start rendering
the image.
I hope this little tutorial can help you on your way to make
universe and space backgrounds for your scenery. Experiment
and have fun!
