Asteroids . . . . .
Ok,
this is part four of the tutorial Planetary Rings in Lightwave 7. If by chance
you came to this page by way of an outside link, You can find the first part of
this Tutorial . . . . HERE
For those continuing on . . This will rap up out Planetary
Ring tutorial . . .
Step 18: Now we get to color our asteroids,
if you switch to the Shading Tab, you will see a control panel
you are familiar with. In the color channel choose a base color you like for your
'roids. I choose something on the grey/blue scale as I am going to make my rings
multi colored. R-88, G-102, B-115. You can also click on the Texture channel
in your color channel and add some extra effect to the color if you want.
Fig 18 
Step 19: Ok . . . Now let give this puppy
some diffuse shall we? Click on the "T" in the diffuse channel and open the editor.
Change the layer type to Gradient, as we want to adjust the perimeters of the
gradient in this section.. Change the Input Parameter to Bump. because this is
were we will add dimension to the channel. Use these parameters:
Key 1:
- Value = 50%
- Parameter = 0.0
Key 2:
- Value = 75%
- Parameter = 0.3
Key 3:
- Value = 80%
- Parameter = 0.6
Key 4:
- Value = 100%
- Parameter = 1.0
Fig 19 
Step 20: Last but not least open the bump
channel and use the settings I have here . .
- Procedural Type: Crumple
- Texture Value: 100%
- Frequencies: 3
- Small Power: 0.7%
This will finish off the textures for the 'roids we are using . . . Like I said
this is only a guide. . If in experimenting with values on your Asteroids you
see something better or something you like more, use it. . Because as our old
friend Bob Ross use to say:
. . "This is your world, you can do what-ever you like".

Step 21: Now lets jump out and see what this
look like in the Viper, switch back to Object Preview and lets see what we have
. . . Not bad at all . . . . . I like it OK
. . Now, 3 more settings to add before we continue . . .
Remember the opening of StartTrek Voyager . . . as the camera pans up through
a Ring System on some planet to reveal Voyager gliding along the outer Asteroid
belt? Remember how Voyager reflected in the Asteroid Ring? . . . lets get some
of that here . . . so apply these settings:
- Specularity: 15
- Glossiness: 7
- Reflection: 12
Fig 21
Step 22: Now that we have this first layer
done, we can copy paste the settings to all the other layers . . . Go to the Hypervoxel
panel and Highlight layer 2, activate this layer. Go back to
layer 1, and at the top of the panel left hand side click copy,
go to layer 2 and click paste. Repeat these steps for all of
you layers and then save the settings for this as Planet_Rings. The save button
is in the same group of buttons as the copy paste buttons.

Now because we have all
of our asteroid rings in different layers we have a lot of control over them.
You can change the size, shape, texture, and color of any of the rings . . . feel
free to do as you like at this point it is all up to you. The last thing to do
here is fire off a render and check out your work . . . .
I hope this tutorial
was help, if you like it let me know, if you use it in a scene, drop me a line
with a link to it as I would like to see what you have done. . see ya'
