FAQ: LegacySO in 3D Mode
23rd June 2025
What was that? LegacySO in 3D? Don’t mind if I do! Read on for instructions on how to enable 3D mode for LegacySO, based on the 3D remesh package from FreeSO’s original run.

Requirements:
- The latest version of the FreeSO 3D remesh package (available here)
- Basic understanding of Windows files (zip, etc)
- 5-10 minutes of your time
How to enable 3D mode:
- Close your copy of LegacySO
- Download the latest version of the FreeSO 3D remesh package
- Extract the contents to your downloads folder (or wherever you want)
- Find your LegacySO game folder (where you launch LegacySO.exe)
- Navigate to ‘Content’ -> ‘MeshReplace’
- Empty the contents of this folder (you will be replacing it with the Remesh Package)
- Move the contents from the ‘MeshReplace’ folder that you downloaded earlier into your game’s ‘MeshReplace’ folder
- Create a new shortcut for LegacySO.exe (If on Windows 11 this is right click -> Show More Options -> Create Shortcut)
- Edit the shortcut and in the ‘Target’ path add -3d (it’s important that the ‘d’ in 3d is lowercase)
- Launch the game from your new shortcut
- If everything worked, your game will now be in 3D!
To revert from 3D to 2D, launch the game from the .exe or make a shortcut without the -3d mode applied.

If you run into any issues, reach out to a team member on the LegacySO Discord. Although 9/10 times these instructions will work, 100% of the time.
