My version of a disco ball that I use on the Opal Star. Coordinates 0,100,0.
IMPORTANT: This has a few separate parts (ungrouped for easy adjustments)
1-Floor and ceiling, throw these away, but they are there so you can see the sparkles.
2- Discoball, don't throw this away silly!
3- Ceiling and floor reflections, these are just the sparkle effect on a couple of flat circles. raise or lower or scale these for your room size, you can change the intensity and color of the sparkles with the color tool (light = more intense, dark = less intense).
Modify however you like!
