[h2]FAQ[/h2]
Here are some important notes about the upcoming tModLoader launch!

  • You do not have to make any backups
  • Simply update Terraria to 1.4 and install tModLoader on Steam
  • You can play vanilla Terraria 1.4 and TML 1.3.5 alongside each other; tModLoader through Steam is treated as a separate game.
  • tModLoader for the 1.4 version of the game will come at a later date.
  • Steam Workshop is not supported as of yet, but is planned.
  • The Mod Browser will exist just as it is now, and we will not force Steam Workshop use
  • You can still use the 64 bit variant of tModLoader
  • With the new release, tModLoader can be installed anywhere regardless of location or whether it is a Steam install.
  • tModLoader will work for Windows, Mac and Linux


How will this affect me? Will my mods still work when Terraria 1.4 is released?
When the Terraria 1.4 update happens, your current Terraria install will automatically update to 1.4, thereby making any non-Steam version of tModLoader unable to load due to these version differences. To fix this, simply install tModLoader via Steam. tModLoader will now be installed independently from Terraria, with a separate entry in your Steam library, allowing you to switch between Terraria and tModLoader just by launching the version of the game you wish to play. Your mods, players, and worlds will all still be there.

Does this mean tModLoader has updated to 1.4?
No, that is still to come. tModLoader on Steam means tModLoader (on 1.3.5) and Terraria (on 1.4) will coexist without any effort from the user.

I currently use tModLoader 64 bit, how will that work?
tModLoader on Steam is launching with the 32 bit version of the application. We are still discussing potential ways to bring 64 bit along perhaps sometime in the future. At the very least, you'll should be able to manually install 64 bit over regular tModLoader (outside of Steam, for now) as in the past. (It'll just be in the tModLoader folder now, instead of Terraria)

What about steam workshop support?
Steam Workshop is planned, but won't be part of the initial release.
Once Steam Workshop is supported, we have no plans to discontinue the in-app Mod Browser.
The Mod Browser will keep functioning, so you can keep downloading mods that do not choose to be hosted on Steam Workshop.
