📋 About This Mod
UPDATED FOR 2025
Thanks to this mod: CustomCraft3, which offers many possibilities, a very good job and all credit goes to MrPurple6411.
This simple mod changes the size of items in your inventory... what more can I say, except... seeds taking up 2x2 spaces?
Seriously?! Where's the logic in that when they're tiny once placed on the ground?
In general, item sizes had been reduced overall, but the mod remains fairly consistent, as some items, such as the Prawn's arms,
have been increased in size from 1x1 to 1x2. The mod also covers a large number of mod items to maintain this consistency.
There is already another mod that use CC3 and modify item sizes: Custom Size Essentials
ALL items in this mod are modified by mine.
So they are inevitably incompatible.
(if you still want to mix them, see details in sticky post)

✨ Key Features
📊 Pros & Cons
✅ Pros
- Fresh update (Feb 2026) — still being worked on.
- Handles modded items, which is a nice touch for modded playthroughs.
- Lightweight UI tweak that doesn't overhaul the game.
⚠️ Cons
- Tiny community (16 endorsements) — you're on your own for troubleshooting.
- May conflict with other inventory mods — no compatibility notes.
For Subnautica players who want a more realistic or organized inventory without a full overhaul. If you're running other mods, this could be a nice QoL addition, but don't expect detailed documentation. Skip if you're fine with vanilla item sizes.
💡 Beginner Tips
- Since it's a UI mod, make sure to install it via a mod manager like BepInEx or Vortex to avoid conflicts.
- Check the mod's page for any required dependencies like BepInEx, even if not listed here.
- Test with your other mods to see if item sizes clash — if so, load order might matter.
