Why does Minecraft say "Made for an older version" with Optimum Realism

It's just a warning, not an error. Click "Yes, I accept the risk" and load the pack — it almost always works fine. The warning fires when the pack's pack_format number doesn't exactly match the format your Minecraft version expects.

Minecraft has tightened its resource pack version checking since 1.9 (back in 2016). The launcher now warns you any time the pack_format number in pack.mcmeta doesn't exactly match what your current Minecraft version expects.

What it usually means: almost nothing. Resource packs are forward and backward compatible across many Minecraft versions — the warning is over-cautious.

What to do:

  • Click "Yes, I accept the risk" when prompted. Load the pack normally.
  • If textures actually break (pink/purple blocks, broken UI), see this page.
  • If you want to silence the warning permanently, edit pack.mcmeta in the .zip and set "pack_format": N to match your Minecraft version.

If you really want the version-matched pack: open /account and pick your Minecraft version from the dropdown — we ship per-version releases for the major versions.
