Core concepts

Modrex is built around a few concepts that stay the same as more games are added. Game pages explain the current values for each game; concept pages explain how those values behave in the app.

Concepts

Section titled “Concepts”
  • Games and targets explains the active game, per-game settings, and target tags such as mods, paks, mod_overrides, and ue4ss_mods.
  • Archives and loaders explains how Modrex classifies downloads, local archives, mixed-target modpacks, and loader dependencies.
  • Priority and state explains visual order, filename prefixes, enabled state, missing files, and .modrex.json.
  • Launch modes explains normal launch, launch without mods, temporary backups, restore behavior, and launch options.

How to use this section

Section titled “How to use this section”

Start with Supported games when you need a game-specific folder or launcher matrix. Use concepts when the same behavior appears across multiple games and you need to understand what Modrex is doing.
