I started to create exo moons and I came across this planet, I believe it and I realized that the ring disappears with distance, I make this post to be able to discuss the subject

[SevenSpheres]

[...]the ring disappears with distance[...]

Celestia Origin solves this problem by defining the rings around a separate, invisible (Mesh "") object, with a radius equal to the outer radius of the rings. Here's the code used:

Code: Select all

      Sunset   [ 0.9 0.3 0.8 ]
   }
   EllipticalOrbit
   {

Thank you very much, tilt the planet to give it the same effect. I will complement it and upload it, if you want, modify it.

[Gurren Lagann]

I'm not sure if 1SWASP J1407b actually has red-white rings, but its 400 ly away, so i cant say for certain.

[Daly]

The color of the rings is not known, but if how much luminosity falls when passing its star with the rings, the rest will be fictitious but this is this image of spece enginer, also it is not known if it is a quasi-star or a supersaturn and if you have a mass of 20 jupiter you could easily have a barycenter far from your stars

[Gurren Lagann]

You mean "brown dwarf", not "quasi-star". Those are two completely separate categories.

[Daly]

from there I make the textures moons.

[DrJMOS]

Hi Daly, I've modified ring texture adding a transparent layer and diffuse the edges of ring texture

New texture here

[SpaceStalker]

Why the code file for planet is .stc? I think it must be .ssc.

[Gurren Lagann]

J1407b has a chance to be a brown dwarf though.

[SpaceStalker]

It probably is a brown dwarf. But such small brown dwarfs look like gas giants, because their nuclear synthesis is wery weak.

This body is young, so it's temperature is caused neither nuclear synthesis, nor star radiation. It hasn't just cooled down yet.

Daly, one of your assets (the night texture) originates from CelWP and was made by me on the 29th of may last year. (For the brown dwarf Auwei) Please change it, it's on wikipedia now. lol
