银河夜空

This node group is aimed to simulate a fake night sky, with random dispersion of stars. In addition, there is a fake Milky Way, with a parametrable density of stars and halo.

To achieve a more realistic earth-based night sky, there is furthermore the possibility to add a horizon color, which fade from ground to zenith. This color influences the brightness of the stars in horizon area, in order to simulate the adjonction of light.

The sky color is the screen on which stars are projected. Sky luminosity have thus an influence on how many and how bright stars are visible. In fact, a day color setup for the sky will produce faint and rare stars, and indiscernable Milky Way halo.
