For the clouds in the second scene, it's just the Starfield module. I wish it a few more options. Specifically:
- The ability to specify the emitter's proportional area and not have it squish the graphics by the same ratio.
The ability to set a fade in and fade out to avoid the layers just disappearing when they hit the plane of the screen.
The ability to Depth Test multiple Starfield modules to facilitate multiple source images (I ended up using a single really wide cloud image).
The ability to hook up multiple inputs and have each input map to an equal percentage of the stars.
Cheers!
