RealGasGiants: Add-on Rings & Ring Generator

This is a set of rings generated by Rattium Shipyards as an add-on to the excellent RealGasGiants mod by Echthros.

It includes 6 new rings to make your custom star system your own! They have been created using a carefully tuned procedural ring generator made especially for this purpose, and include gaps, color variations, alpha grading, sub-rings, and small scale visual banding that only becomes apparent when close.

To use these ring textures, begin by following Echthros' instructions to spawn in your gas giants, save your world, and then, in the RealGasGiants config in your world-save, change the <RingSkin> </RingSkin> entry for the gas giant(s) you want to modify to "Rattium1", "Rattium2", "Rattium3", "Rattium4", "Rattium5", or "Rattium6" - these are the rings shown in the pictures, in that order.

Besides RealGasGiants and this mod itself, two additional mods were used in the creation of these images: RealGasGiants - AddOn Planet Skins, which directly inspired this mod; and the Space Just Got Real - Night Time Fix mod.

The RealGasGiants settings for the planets in the screenshots have been changed as follows, but are otherwise the defaults:
-they use RealGasGiants - AddOn Planet Skins
-RingLightMult and RingShadowMult are both set to 0.01
-RingLayerSpacingScale is set to 0.05



Additionally, the generator itself is made available by Rattium (that's us) on GitHub[github.com] under an MIT license.
===============================================================
For those that care, the generator uses a Monte Carlo algorithm to generate the sizes, positions, and large-scale coloration of the rings and sub-rings. Fine banding is then added with Gaussian noise spectra for the color channels, centered at the local large-scale ring color.

Using the generator code, gaps can be added in pre-defined locations in order to accommodate specific planet-moon distances, or just for a preferred aesthetic. Many of the other parameters are also easily tunable.

Please credit this mod if you use the generator!
