This modpack, as showed in the title, is able to run with newer versions of Java (17/21/25/26 ...)We feature Java 25 as the main version for bug-testing, but any other version should work*

Upon launching, the game will open a white window, asking you in which Java version you want to run the game. You'll need to install Java from here, then to install wherever you want.
Once it is installed, remember where you installed it !
Go back to the white window, click the Add button in the top right corner, and go where you just installed your new Java 25. In there, enter the folder named bin, then selected javaw.exe.

Then select the maximum of RAM you want to allocate through the slider (don't go higher than 10 Gigs, it can bring issues with your garbage collector), then press Run !

Each time you'll want to run the game, you'll just have to press Run on that white window, and it shall launch. You can also add multiple Java versions/profiles through the same process.

Additionnal info for reporting issues & bugs :

Any issue related to the modpack will be considered worth looking at if you're able to reproduce it with Java 25 installed ; on the other hand, any issue related to shaders WILL BE IGNORED.
Shaders are present as a feature, but are incompatible with lot of features from BetterFoliage and other mods. BetterFoliage can be quickly disabled in game with F8, then setting to false.
