16/10/2018 - Version 2.10.3:

• Fixing a newly introduced bug in the visuals of the gaps in the rings.

13/10/2018 - Version 2.10.2:

• some more minor optimizations.

09/10/2018 - Version 2.10.1:

• more optimizations.
• rings get more transparent when entering an atmosphere.

09/10/2018 - Version 2.10:

• optimized some of the shader's code (thanks Svengali!).

07/10/2018 - Version 2.9:

• better handling of the alpha channel .

23/09/2017 - Version 2.8.1:

• bug in the description text now properly solved, it was still present due to a small oversight (thanks again, Cody).

23/09/2017 - Version 2.8:

• changed description text to "This planet has rings."
• fixed a bug in which the description text appears many times (thanks Cody and Norby).

19/09/2017 - Version 2.7:

• added "use strict"; to scripts which removes some warnings in the log.
• rings are now a little bit more common (1/8 of planets will have them).
• the description of a system will now tell whether it has rings or not (thanks phkb for the help implementing this!).
• close-up grain density now proportional to the colour intensity of the ring lane.
• fixed bug in which Ribior's main station would spawn inside rings (thanks to spara, cim and all others for the suggestions and spara for doing the all hard work for the fix).

27/08/2017 - Version 2.6:

• the sinusoidal functions which create the variations of colour intensity now fade in one by one according to the distance, which solves the Moire pattern problems.
• shading applied at close distances so that the grains look like rocks.

17/08/2017 - Version 2.5:

• fix for a small bug affecting certain cards (wrong type for second argument of pow).

03/08/2017 - Version 2.4:

• change to shader to fix a bug with certain ATI cards.

24/07/2017 - Version 2.3:

• code refactoring.
• rings fade into blue when entering the atmosphere (such as when using PlanetFall).

20/07/2017 - Version 2.2:

• smaller ring bands and grains only visible at closer distance.
• improved the issues with moire pattern, in particular at lower resolutions.

20/07/2017 - Version 2.1:

• the large gaps in the rings are now randomized making each system more unique.
• the colour gradient function is also randomized for more unique rings.
• renamed the effect script.

19/07/2017 - Version 2.0:

• rings now have different relative sizes to the planet.
• they also have different radial length.
• applied a slight yellow tint.
• applied ambient light.
• shadows are darker.
• changed the spawning algorithm which, among other things, make the rings more common.
• ring now uses a colour gradient instead of a texture (which is now only used to generate noise).

Version 1.2:

• use 1.80 features, repackage.

Version 1.1:

• improved ring texture and appearance contributed by ZygoUgo.

Version 1.0:

• initial non-beta release.

Requirements

A shader-supporting graphics card is required, the more recent the better. Older shader-supporting cards may be too slow to render the rings at an adequate framerate.
