How to get custom artwork in your base.

its pretty simple tbh, just not well known.

Step 1

go to the steam apps folder, find subnautica. ( usually under common. )

Step 2

go to the snappdata folder.

Step 3

after navigating to the save data folder, find your appropriate save game's folder.

Step 4

find the screenshot folder within that save game's folder.

Step 5

deposit your art/photo into the screenshot folder.

Step 6

boot up subnautica. build and place a picture frame. if you did this correctly, you should see the previous images you placed show up as screenshots.

and it should look something like this!
