Important Breaking Change

Overlays are now correctly stored per-dimension. After updating:

  • If you only used Underlay in the Overworld, nothing changes, you're good to go!
  • If you placed overlays in other dimensions (Nether, End, etc.), the old save file (underlays.dat) will be treated as if it belonged to the Overworld. You’ll need to:
  1. Load your world and remove any Nether/End overlays while in the Overworld.
  2. Travel back to those dimensions and re-place them there.

Other notable changes:

  • Exclude tags actually work now
  • Fixed overlays disappearing after changing dimensions (#8)
  • Fixed rendering issues on Neo/Forge
  • Added support for 1.21.6

  • You can now break an overlay just like any other block - no more weird shift + right click. (Thanks @LX86!)
  • Added exclude tags, so you can prevent specific overlays from acting as overlays.
  • Introduced experimental Neo/Forge support (currently only for Minecraft 1.20.1 and 1.21/1.21.1).
