Hi again, Nauviax!
I noticed, that not all moon-planets are visible for some of the parent planets, for example Vesta:


Is this possible to catch from PlanetsLib and fix?
For that exact scenario I used mod Better Planets

Could you provide a log file? Visible planets should log reasons for skipping certain planets/moons, assuming the moon is set up correctly in planets-lib. (planet.orbit.parent)

Depending on how better-planets is setting up moons, it may also be worth adding visible-planets as an optional dependency to resolve load order issues.

I see that it's adding them in the log, but not visualizing in the game. Making visible planets as dependency not fixed the issue.

For example, for Vulcanus 2 new moons Zzhora and Froodara, works correctly:

I'm thinking, maybe they just overlaps each other in one position? Is it possible?

After a bit of testing, I can confirm all the renders are being overlapped. Turns out the formula I used was just bad and broke at 3 moons.
1.6.0 will contain a fix, and some setting changes for better positioning.

Default is still even spacing

Side note: How do you embed images I've forgotten and can't figure it out aaa

It works perfect, thanks!!!
About screenshots, I use this format:

I'm also wondering if it's possible to render moons based on their positions relative to the parent planet?
For example, the planet Zzhora should appear closer because its orbital distance is smaller than Froodara's.
The angle should match the one used that planet rotates around its parent.

It’s a neat idea, but it’d have to wait until I have more time as I’m really only prioritising bug fixes at the moment. You’re more than welcome to take a shot at it and open a pr, or you can edit the distances in the sprite prototypes in your own mod’s final-fixes by editing the shift values of each layer.

I don’t want to spam the discussions, so I’ll ask about another possible feature here instead:
Is it possible for your mod to make planets and moons rotate independently of each other?
Right now, a planet or moon seems to rotate together with its parent body (or other planets), which looks a bit weird.

Almost certainly not, the sprite is built in the prototype stage so I can’t animate them separately at runtime. (I’m 95% sure anyway)

PlanetsLib support was really just a bonus feature for the mod, and I don’t plan on reworking it to make it fancier than it’s current state.

I’m afraid outside of very simple feature requests, you may need to look into making PRs for the mod if you want some of these implemented.

I think it would be possible by implementing reverse rotation to the moons (or to the parent), so it will look like planet stay still, no?

Again, the moons and planets are the same sprite at runtime. Afaik, they can not be rotated separately as-is.

You will need to open a PR if you want this feature, I don’t currently have the free time to rework planetslib support to allow this.

(Also please keep feature requests outside of bug reports)
