Genesis Stars and Point Clouds

Basically the stars are a particle system that is rendered out into a point cloud to be used to light the smoke. Previously I was trying to accomplish this by instancing lights on each point. The point clouds are a little bit more complicated to set up( I had to write some VEX code) but they render much faster. Also since I can use the point clouds as the star geometry they have no real downside to my project size for the renderfarm.

The image above is composited from four passes, Nebual, Nebula Pointcloud, Background, and Stars. Later I might post a explanation of my compositing since there are some cool things going on like RGB lighting.
