In the event you don't have the picture frame unlocked open up the console via hitting F3 & F8. Once this is done, hit disable console and hit the tilde ` button. Type in unlock pictureframe. You are now ready to go.
Installation instructions:
Because of the way the game's files are set up, this has to be manually installed. This was the easiest way I could find to locate the correct save as you're not able to name your game and they don't seem to be in any kind of order. If somebody else knows an easier way, please let me know and I'll update this.
1) Open your preferred saved game and take a screenshot. Doesn't matter of what, just make sure you remember what it looks like (if you've already got a couple, you can use those instead). This will just be to help locate the correct save file.
2) Open your main Subnautica Below Zero folder (usually C:\Program Files\Steam\steamapps\common\SubnauticaZero)
3) Open the 'SNAppData' folder and then 'SavedGames'
4) You will see a list of folders called 'slot(xxx)'. Open each one and open the 'Screenshots' folder inside. Once you find the picture you took earlier, extract all of the mod's files into that same folder. If you have multiple games you'd like to stick the pictures in, you can do this again for each one.
We have added in all the data entries from both Subnautica and Below Zero. Since it's a manual install, it's also pretty easy to just delete any creatures you don't want.
