Client

Optium optimizes the game and adds the ability to customize the game, like in Optifine

Resource packs and more

Optium is a modpack that allows you to install any resource pack created for Optifine! Modpack based on Sodium

Resource packs:

Dramatic sky
Fresh animations
bare bones

Where were the mods installed from?

All mods and resource packs from the modpack were installed in the Modrinth App when installing mods and resource packs, no third-party sites were used which may pose a danger to ordinary users

Not required reading

I'll say in advance that there probably won't be a modpack for two versions 1.16.5 and 1.17.1 because there is a mod for Fresh animations starting from 1.18.2 I'll probably make a modpack for 1.16.5 and 1.17.1, but without Fresh animations support, definitely do not add to the MemoryLeakFix modpack minecraft will not be able to start this description will be updated

How to install Optium

With Millida Launcher

Install Millida Launcher
The launcher is free: download it at millida.net/launcher and sign in with any nickname.
Click “Install” on this page
The launcher opens and installs the modpack for Minecraft 1.18.2–1.21 on Fabric automatically.
Launch the game
A profile with it appears in the launcher: click “Play”.

Manually

Download the modpack archive
In the version list above, pick the file Optium RC 0.7.7 0.7.7.mrpack (18 KB).
Import it into a launcher
A launcher that supports modpacks (Millida Launcher, Prism) takes the archive via “Add modpack”, then “From file”. No need to unpack it yourself.
Allocate memory
Modpacks need more memory than the plain game: set 4–6 GB in the profile settings.

Minecraft 1.21 runs on Java 21: with a different Java version the game may close right after launch.
