iridescentcraft.batto a folder of your choice (Desktop, Downloads, anywhere). - Double-click the bat. It will:
- Download and install PrismLauncher if you don't have it
- Create the IridescentCraft instance with all 420+ mods
- Configure the per-launch sync hook so your pack stays current automatically
- Set the required JVM flags
- Open PrismLauncher → click IridescentCraft → Launch.
If you ran the installer before today's bat update, re-running it once will pick up the new auto-sync wiring.
The test server has a whitelist. Before your first join, send the server operator your exact in-game name, capitals included, and wait for them to confirm you were added.
- "You are not white-listed on this server!" means your name is not on the list yet, or it was entered with different capitals. Send the operator the name exactly as the game shows it.
- If you change your in-game name, you have to be added again under the new one.

Alpha. Active development. Bugs expected — please report via Discord (or GitHub issues if you have access). Save backups before updates; data formats can change between cycles.
The pack auto-syncs on launch via a per-instance pre-launch hook (set up by the installer). New tester instances pick up updates automatically; no manual re-installs needed for routine pack changes.
All mod licenses retained per their original mods. Custom code in iridescent-*-mod/ directories is the author's. See individual mod credits via the in-game Iridescent Codex Patchouli book.
