Too Many Rooms — Free Building

[line]

Description

TooManyRooms removes base placement collision restrictions in Subnautica 2, allowing you to build your habitat freely disabling the overdone obstruction boundaries when placing and resizing rooms.

✅ What this mod does:

• Removes collision restrictions when placing base rooms and extensions[/*]

• Lets you build in areas that would normally be flagged as invalid[/*]

❌ What this mod does NOT do (yet):

• Free placement inside the base (building furniture/items inside rooms) this uses a different system and is not affected (will come later)[/*]

• Fix or counteract the "Cannot deconstruct: has attachments" bug ( check my post )[/*]

[line]

How it works

This is a C++ DLL mod loaded by UE4SS. It patches two memory locations at runtime to bypass the placement validation checks. No game files are modified the patch is applied in memory only and disappears when you close the game.

⚠️ Common Installation Mistakes

Please read before posting a bug report!

• UE4SS and dwmapi.dll must be extracted directly into Win64 or WinGDK — not inside a subfolder[/*]

• TooManyRooms must be placed directly inside Mods — not nested inside another folder[/*]

• When unzipping, make sure to move TooManyRooms out of any parent folder created by your unzip tool[/*]

• enabled.txt must be present inside the TooManyRooms folder[/*]

[line]

Installation

• Install UE4SS for Subnautica 2[/*]

• Locate your Mods folder:

Steam:

Subnautica2 Binaries Win64 ue4ss Mods

Microsoft Store / Game Pass:

Subnautica2 Binaries WinGDK ue4ss Mods [/*]

• Extract the ZIP and place the TooManyRooms folder directly into Mods [/*]

• Launch the game — placement restrictions are now removed[/*]

Result:

ue4ss + dwmapi.dll /

    └── TooManyRooms/

        ├── enabled.txt

        ├── Scripts/

❓ FAQ

Q: Will this corrupt my save?

A: The patch is applied in memory only no game files are modified. Removing the mod folder is enough to fully uninstall.

Q: Can I remove the mod mid-playthrough?

A: Yes — delete the TooManyRooms folder. No files are modified.

Q: The mod doesn't seem to work?

A: Almost always a folder structure issue check the Common Installation Mistakes section above. Also make sure enabled.txt is present.

Q: Does the mod send any data externally?

A: No. No telemetry, no external calls. Fully local and open source.

Q: Does it affect building furniture inside the base?

A: No inside-base building uses a separate system. Only external base placement is affected for now.

Q: Is this mod dangerous?

A: Only for your base's structural integrity. 🪸
