Black Hole Development.

[Starcow19]

I am new to the modding community and am trying to make a black hole for my game. I play with RSS and Constellation so my idea was to copy a star file from constellation and edit that. Originally it worked, and I can make new stars pretty easily. The problems I have is in making planets orbit the star. If I change a planet file so it has a new reference body it resets the game to stock. Anyone having this issue. Any help welcomed. End game goal is to make a black hole system in either stock or RSS that will have a realistic looking black hole with a well textured accretion disk. If I take the code to generate a ring and add two rings at 90 degree angles of eachother we can make what looks likes relativity effects on a black hole. If we set the perpendicular ring to always face the player in the same way then the effect should be convincing. What more if we could get clouds from a visual pack onto the accretion disk it would really improve the way the black hole looks. This might be difficult to visualize but essentially the goal is to make something that looks like this:

Once we can get a good black hole I would like to move on to adding planets that orbit the black hole and also giving the planets moons. I want to make each planet interesting and worth visiting. Ideally I'll do this in RSS but we could always release a stock version too. Any help on how to mod this would be appreciated and I'd love to work with someone on this.

There is already a mod that does exactly what you're looking for, albeit tuned to stockalike sizes.

It's mostly a Kopernicus config with visual enhancements and some planets with a custom plugin for the black hole's visuals. You can look through the configs to see how the author goes about this.

However, since you're tuning your mod to Real Solar System, you're black hole needs to match the range of real world supermassive black holes. Interstellar's Gargantua is around the size of most supermassive black holes at 100 million solar masses (1.98*10³⁸ kilograms). I calculated the diameter and got, well, a ridiculous number at 156843367301735344213639569... somethings.  No idea if that's in meters or kilometers, I'll have to ask around. If you want realism, that's how big and heavy your black hole needs to be.
It also needs to be an absurd distance away, for obvious reasons. You could put it at the center of the galaxy, at 25,000 light years away, but then you have Sagittarius A* - the Milky Way black hole - not Gargantua... But I'll leave that up to you.

Oh, and you need to re-parent kerbol The Sun to that monstrosity, for even more realism. There is at least one mod that does just that, but with it's own parent - namely Galactic Neighborhood.

I have no idea how KSP would handle such a beast... it may or may not crash upon attempting to load it in the tracking station.

You'll have to ask someone else for help with getting it to co-operate with RSS though, especially if you re-parent RSS. I suggest making it orbit the stock system at your preferred distance when testing it and then re-parent the sun to it when everything's finalized.

I'll probably just play around with the configs till I get it right, and then retexture. Originally it'll orbit Kerbol and just be a small black hole for testing purposes, but then I'll jack it up big. Realistically I'll probably make it a tenth or hundredth the density of a black hole just so the numbers don't get crazy in terms of orbital velocity.

It sounds like you're working on modding the game yourself rather than suggesting something for the stock game, and so your thread has been moved to add-on development. Have fun with it.
