Dear Nauviax,

I am writing to express my appreciation for your Visible Planets mod, which adds a captivating visual dimension to the Factorio universe. The addition of planet rendering and animations is truly impressive.

I am reaching out to request a feature that would greatly enhance the mod's appeal: compatibility with the Real Starry Universe mod. Integrating these two mods would create a stunningly realistic and immersive space experience within Factorio.

The Real Starry Universe mod introduces a vast, procedurally generated star system with realistic star and planet placements. By enabling Visible Planets to render these planets, players could enjoy a seamless and visually stunning transition from space travel to planetary exploration.

I understand that this request may involve significant development effort, but I believe that the potential benefits for the Factorio community would be substantial. If you are open to considering this feature, I would be more than happy to provide any assistance or resources that may be helpful.

Thank you for your time and consideration. I look forward to your response.

Maybe it is possible to make an API for other mods to define high-resolution images of their planets so they can be displayed?

That would be smart, but instead I'm working on manually adding compatibility. (Along with a few other planet mods I know of)
I'll look into an API implementation later, I haven't messed with that before.

You can add a background to the planet by default, using the icon that comes with the mod. Then add a property to disable it.

It should be working, and it'll be uploaded in a moment. Some planets like earth are a bit funky as the sprite provided by your mod doesn't have a transparent background, but otherwise it works fine.

Eventually I'll get around to adding an API of sorts. It'll probably also have options for planet scale too, assuming I get around to it.

The lack of a transparent background is only temporary.

add a GitHub repo？

Sure why not.

Team Starts for Multiplayer
ERM

These 2 mods add new planets

Team Starts adds many duplicate planets, so I'd like to implement some sort of API that they'll be able to call on their side to register with this mod. I'll probably get around to doing this sometime this week. (Manually adding compatibility for upwards of possibly 50+ planets would be silly, and it's not the only mod that does this sort of thing.)

ERM seems to add two planets from the looks of the mod gallery, but I can't for the life of me find any reference to them in the source code. Searching for "char" and "aiur" results in nothing in the base mod, and there are WAY too many dependencies for me to go through right now. I'll likely have another look later, but if you can confirm the space-location internal names and sprite paths, then I can add compatibility for them. (Or wait for aforementioned API)

Probably worth creating a new thread next time though, as this one is starting to get off topic.
