A big modpack that combines some big mods like The Aether II or Tinker's Construct, small mods that improve game experience and some mods that are just little tweaks to vanilla minecraft.
With this modpack, you can create all kinds of drills and quarrys, conquer new dimensions and even more…

It is recommended that you allocate at least 6144Mo/MB of RAM to Minecraft in order to be able to take full advantage of the modpack.
To do so, on the Twitch launcher, go to the "The Transpack" profile, click on the gear, uncheck "use system memory settings" and drag the slider until you reach the desired amount of RAM.

⚠️ Important: The modpack does not include OptiFine, you will have to install it yourself if you wish to take advantage of it. ⚠️
Installation instructions for OptiFine:
- Go to https://optifine.net/downloads
- Download "OptiFine 1.12.2 HD U F5"
- Move the downloaded file to the following folder: "%userprofile%\Twitch\Minecraft\Instances\The Transpack\mods" (most of the time %userprofile% corresponds to "C:\Users\[username]")
(Or click on the gear, then "open folder" and put OptiFine in the "mods" folder)
