In the Hyper Voxelsmenu, set the size to about 10 meters.• To make the asteroids more random, set the Size Variation to 200%.Step 3: Layout: The Rocks• In Viper, select ‘Particle Preview’ under ‘Preview Options.’ This allows you to work with just one asteroid, instead of all of them.• In the Hyper Voxels menu, go to ‘Hyper Texture.’• Look through the different texture until you find one you like.• Pictured, is Smokey1, but Dented works very well, too.• Play with the various settings until you’re happy.Step 3: Continued• Go to the ‘Shading’ tab in Hyper Voxels.• Choose a base color, then press the ‘T’ next to it.• Select a texture map you like.• If you want, you can add multiple layers, but it’s not necessary.Step 3: Continued• In the ‘Diffuse’ channel, add a gradient.• Parameter 0.0 = Value 50%• Parameter 0.2 = Value 75%• Parameter 1.0 = Value 100%• Of course, these settings are just a suggestion to get the inside darker.Step 3: Continued• Add a texture under the ‘Bump’ channel.• Set a ‘Procedural Texture’ to use the ‘Crumple’ texture.• Alter the settings to get a nice effect.Step 4: Render• You should get something that looks like this…• It’s a very nice asteroid field.• After doing all this, you should adjust your lighting to match whatever you’re trying to do.• Original Tutorial:
