Installation

  1. Download the .mrpack file for your version and renderer.
  2. Open Prism Launcher, Modrinth App, or any launcher that supports the mrpack format.
  3. Import the pack: Add Instance → Import from file (Prism) or Import (Modrinth App).
  4. Set Java 21 in instance settings if available.
  5. Allocate 4–6 GB of RAM for best results.

Format Info

OptiArk uses the .mrpack standard (Modrinth Pack Format). Mods are downloaded directly from Modrinth on first launch, the pack file itself is small.


Legacy versions (1.21.10 and below) were distributed as .zip files. These are still available in the GitHub releases archive but are no longer supported.
