Custom Dimensions

v1.0.1 Changelog 🛠️

• Fixed portal height collapse 🌌: Target portals no longer flatten to 1 block tall. Each interior position now preserves its relative Y offset (targetY + (p.getY() - sourceMinY)) instead of all sharing the same Y level.
• Fixed portals spawning at bedrock 🪨: findSafeYOffset now scans from world top to bottom at target coordinates, placing portals on the surface. Void dimensions now fall back to Y=64 instead of Y=-64.
• Fixed void dimension terrain 🗺️: 26.x now uses FlatLevelSource with FlatLevelGeneratorSettings (empty layers + THE_VOID biome) instead of a nonexistent API.
• Fixed 26.2.x NetherPortalBlockMixin crash 💥: Removed injection into a tick method that doesn't exist in 26.x.
• Fixed 26.2.x duplicate code 📋: Removed duplicate lines in DimensionManager.createLevelStem.
• Fixed 26.x compilation error 💻: Resolved the Registry.getHolder → HolderGetter.getOrThrow compilation break on 26.x.

⚠️ What Wasn't Fixed & Upcoming Work

• Portal Linking & Two-Way Travel 🔄: True two-way portal linking is currently not working perfectly in this release.
• What we are working on next ⚙️: We are actively rewriting the destination caching logic to ensure that when you step through a custom portal, you can reliably walk right back through the exact same portal to return to your original location. Expect this fix in the next update!
