Secondly, you’re going to install the “FTB Revelation (v3.3.0)” modpack under “Browser” on the FTP App.
By default, FTB App will prompt for you to download v3.4.0, however you MUST use v.3.3.0 in order to log onto UT Dallas Minecraft.
To select which version to install, click “Versions” once you have selected the FTB Revelations modpack, and then click “FTB Revelation – 3.3.0” and click install.
IMPORTANT: After you’ve installed FTB Revelation, you will need to allocate more RAM memory in order for the game to run smoothly. Head over to Settings > Instance Memory to allocate enough RAM (depending on your computer 6-8GB is ideal, however you do not want to allocate all of your computer’s RAM to FTB).
Once you have installed FTB Revelation v3.3.0 and configured it properly, you will click “Play” in the FTB App Launcher. You’ll be redirected to the normal Minecraft Launcher and then proceed to click Play again (you should see your version display FTB Revelation 1.12.2-forge… in the launcher).
Your first time launching FTB Revelation will be a bit longer than normal to install all of the mods.
Once the game has loaded, head over to Multiplayer and click “Add Server”. For Server Name put “UT Dallas Minecraft” or whatever you’d like, and for the Server Address put “mc.utdesports.com”. Click Done and then Join Server, and boom you’ll now be able to begin your adventure!
