Okay. Here it is.
Instructions -
If you only want the asteroid field (beginning of a ring), go into the Node Network and delete out everything in your Terrain and Shader containers. Delete everything in your Object container, except the Background node. Delete the atmosphere, if you wish. Stretch out the Terrain, Shader, and Object containers like the first picture.
Insert the TGC file. Fit everything in - the top row has the Terrain nodes, the second and third rows has the Shaders nodes, and underneath the Base Colours are all of the Object Nodes (planets). You can control the sizes of the asteroids from the Terrain nodes as well as the Shader nodes, but it's easier to change the Terrain nodes to affect the whole structure.
I've included a Render Camera in the TGC file, which will leave your point of view just above the asteroids. To use the camera, connect it to the Renderers and then you can delete the old Render Camera. (see second picture)
Now, to figure out how to increase its size without copying over the top of everything...
