The Beyond reshapes the End into floating islands and sprawling, macro-scale biomes, but almost every other End mod was built for the old flat End, so their biomes, structures, and tooling no longer line up. Isleweaver weaves them back in: it settles foreign biomes onto Beyond's islands and smooths the rough edges, so nothing floats in the void or vanishes out of sight. Best of all, most of it is automatic, with no config to touch.
Requires The Beyond. It only acts while Beyond owns the End, and each mod-specific fix activates only when that mod is installed.
Any End mod whose biomes use the standard tags (minecraft:is_end or c:is_end_biome, shared by NeoForge and Fabric) is auto-discovered and merged into Beyond's End: no per-mod code, no hardcoded IDs. Fabric-port mods that inject through TheEndBiomeSource are caught too, and foreign surface rules are preserved so biomes keep their own look. Mods can extend the scan via BeyondBiomeTagScanRegistry (extra tags) or BeyondBiomeDiscoveryEvent (hand over biomes the scan can't see).
Some mods need hand-written fixes on top of the automatic layer. Each loads only when that mod is installed.
| Mod | What Isleweaver does |
|---|---|
| Astrological | Stops it overriding Beyond's sky/dimension and raises the End's height limits (-256 to 384) so both fit. |
| Enderscape | Lets its decorations fill the deep End below y=0 (where they used to vanish) and widens the End's range to -64–320. |
| Stellarity | Steps aside so its exit portal and altar build correctly, clearing the vanilla pieces and default pillars first. |
| Quark | Points its spire generator at the real island surface instead of the empty top of the world. |
| Phantasm | Adds a safety check so its dragon-mint plant skips foreign blocks instead of crashing. |
| Dimensional Tears | Turns off its End liquid layer so Beyond's auroracite islands stay exposed. |
| Unusual End | Gives the warped reef large coherent regions and places its floating features at island height. |
| Oak's End / Oak Frontier | Reads their Fabric-style biome list (invisible to Beyond) and feeds it into the End. |
Isleweaver builds only on Beyond's public com.thebeyond.api.* (never internal classes) across events, worldgen, compat, and registry (biome discovery, macro regions, surface rules, terrain samplers, coordinate translation). Each integration is a standalone module (compat.<mod> / mixin.<mod>) gated by ModList.isLoaded(...), so one can never affect another.
The Beyond's API is resolved from CurseForge through CurseMaven, so building is just:
./gradlew build # build the jar
