📋 About This Mod
Unlock modded Sea Truck and Seamoth modules naturally via discoveries in Survival Mode(s), instead of having to spawn them in or be in Creative Mode to get them.
DESCRIPTION
With mods, you can now have a Seamoth in Subnautica: Below Zero. You can even have all the cool modules from Subnautica, and even more using other mods, like more depth modules and a thermal charger module. The Sea Truck also has a cut-content "Energy Efficiency" module.
HOWEVER, many of those modules are not set up to be unlockable in Survival Mode(s), so they're only available in Creative Mode or by spawning them in. This mod changes that, by adding discovery requirements to them, so you unlock them naturally while playing.
The Seamoth itself and each module gets 1-2 requirements for unlocking, pertaining to their recipes. The progression should seem like unlocks in the vanilla game. The Seamoth only requires you to unlock the Mobile Vehicle Bay.
NOTE: I've ignored anything added by the "Upgraded Vehicles" mod, since they work fine as-is.
INSTALLATION
Install Custom Craft 3 (Purple Edition) first !!!
Then, just unpack this mod directly into your SubnauticaZero/BepInEx/plugins/ folder.
You should end up with 2 files like this:

CUSTOMIZABILITY
You can add more, by editing the files manually, if you know what you're doing ;)
