My mod never did anything with gravity (nor was that in my intended scope). But because the gravity in my ships is basically vanilla, I'm betting there's other mods out there that affect gravity as you desire, and they should not clash with this mod.

That's odd actually. Because vanilla ships have 0 gravity outside of them. If you spawn anything outside of the ship it does not move at all.
That's why I assumed that you changed the gravity to make building ships easier.

are you maybe mixing my mod up with the byos implementation of FU? thats a different mod that uses the same name for a similar functionality. they did a lot more with it though.

I don't know really, because I never played FU that far. The research system made me uninstall it instant.

So what I am talking about is... On a vanilla ship, if you use /spawnitem with you cursor outside of your ship, you will see that the spawned item stays in place. That is because the gravity outside of the ship is 0. That is why I assumed that it is the case with your mod also and you altered it to make it easier to build.

But... I found a solution to the problem... I created my own mod to deal with that gravity stuff

Vanilla ships don't really have 0 gravity outside them. With vanilla, outside the ship is filled with solid but invisible blocks. So you where really spawning the items into a wall.
