About

This OXP adds some dust rings to a few planets in each galaxy. Whether those rings are traditional gas giant rings or debris rings from industry or long-past battles depends on your planet texture OXP. 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.

Version history

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.
