No Man's Sky Save Editor

No Man’s Sky Save Editor (for FRONTIERS)

by Dona

No Man’s Sky Save Editor has evolved into a very useful tool. After many frustrating searches for a solution, I came across a save editor that allowed me to make changes to the save file, but it was very limited in what it could do, and unless you were very careful, you could completely mess up your save file. So I decided to rewrite it in Java for fun, with a simpler user interface, and as I dug deeper and added more functionality, I decided to make it available to the public.

Frequently Asked Questions


Why can’t I change the stack size on General inventory of No Man’s Sky Save Editor?

In the game itself a number of bugs occurred when this was tried, so it was disabled in the editor. It only works on some types of inventory where the game doesn’t do a validity check.

Why can’t I move my Jetpack to the Technology inventory of No Man’s Sky Save Editor?

The game itself checks if your Jetpack exists (because it is required to play the game), but it only checks the General inventory section. If the Jetpack doesn’t exist there, it will automatically create a new Jetpack. You can move it to other slots in the General section without issues though.

Why doesn’t the ship seed from [some site] work?

New ship models were added in the NEXT update, and many websites that hosted ship seeds have not been updated. There is a way to make the game use the older models, but you would need to use the JSON editor to do this.

Why does the terrain appear inside my base buildings when I restore from a backup?

The game itself doesn’t store all terrain modifications indefinately, and over time even unedited saves with underground bases can fill up with dirt. This is a known bug in the game which needs to be fixed, and when it is eventually fixed it would likely solve the issue with restores at the same time. We will just need to wait and see.

How do I use the “Move Base Computer” function of No Man’s Sky Save Editor?

In the game itself, you must place a Signal Booster in the position where you want your base computer to be. The save editor will swap the positions of the Base Computer and Signal Booster.

I have enjoyed using the NMS Save Editor. Thank you for all your hard work. I have many bases in NMS but one of my low orbit bases I accidently placed the base computer a little too high and now I can’t see it or access it. I would like to keep the location and would like to use your move base computer location option but when I go to the “base” tab none of my bases show up in the pull down menu. All my bases are in the JSON file so I know they are there but again, the NMS Save Editor doesn’t show them in the “base” tab. Any ideas why this is happening.

Thank you for your time.

Would love your thoughts, please comment.x
