If you increase gravity, the radius gets bigger. Since it's a black hole I just set gravity to 100000g, hence the large radius. But if you find a way to change the falloff or the radius please tell me.
For the black surface. It's actually the atmosphere. I just set RayleighHeight, MieHeight and MieG to 0. Idk why but this turns the atmosphere black.

Ah ok, thank you for the reply and sorry for my post moved too soon.
Your work has been added my favories (can be an accretion disc soon but at the moment there is no possibility to do so).

@quarior14 Accretion disc is beyond my modding capabilites. Sorry! But I think it would be possible.

I found it on YouTube, for cons I do not know how he did it :

And given the time, it was before the planets so I'm not sure if we can still do that now.

It is possible, but like I said: I can't do it.

I'm dreaming, that's what I need if I have to gaseous planets génates or ice, well I'm not too detail because it will be out about (and I'm no expert coding planets).
In fact, you have other planets in mind, I look for planets to Miller ocean, cold desert Mann (I took the moment Europe but I do not know if it is good) and Edmunds.

If you get to the event horizon, do you just go through the planet, or do you smash into something. I was expecting to smah into a planet surface or something, but I didn't. I am extremely confused.

@Nicolas Cage You should smash into a surface eventually, because there's a voxel there in there. Are you using a speedmod? Maybe you glitched through the surface. Also nobody knows what happens beyond the event horizon, normal physics don't apply there :P

@Sebastitan I do not have a speed mod, but I kept falling and falling, and eventually I got to 145 m/s, in a ship and out of one. Then I fell through the surface and once I got to the center, I stopped and spun uncontrollably. Very weird...

@Nicolas Cage I tested it and it seems like everything will glitch through the surface and then stop at the center. I can't do anything about that unfortunately. I am working on deleting all blocks that fall into the black hole, but no luck so far.

Perhaps you could use some mechanics of this mod http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=572497877 (the part that destroys your ship if you enter the atmosphere too fast). That way you could damage a ship by X distance to the event horizon until it gets obliterated before hits the "surface" (sorry about my bad english, i'm from Chile). Nice work by the way.

Is it just a planet with realy strong gracity and no hitbox.

Is it possible to use the surface rocks feature to make an asteroid field in the lower grav areas (5-20 G's)?

I am having an issue where this thing looks like a cube instead of s sphere, and it is visible through everything.. players/planets/ships... from any distance. Did I break it somehow, and how do I fix it?

As far as getting rid of objects in the black hole... when this thing was working, it destroyed my ships and killed players in survival. I was under the assumption there was a pinpoint of voxel in the middle that acted like a shredding point as the ships and players oscillate back and forth.
