About this project
What does Astral Building add?
🌌 Astral Building
The ultimate construction utility. Say goodbye to scaffolding, tedious block-swapping, and phantom attacks while working on your megabuilds. Astral Building introduces the Astral Building Nexus, a technological marvel that grants you a localized, highly-protected creative flight zone in survival Minecraft. Designed to work flawlessly with Astral Storage, this mod turns massive base-building from a chore into an absolute dream.
✨ Key Features
- Localized Creative Flight: Right-click the Nexus with an empty hand to launch into the air! You gain full creative flight within a massive 128x128x128 holographic building zone.
- Astral Storage Auto-Refill: Never open a chest while building again. When placed near an Astral Chest, your hotbar stacks will automatically and instantly refill from the chest's 10-million-item database as you place blocks.
- Hostile Evacuation Zone: Building at night is finally safe. The Nexus projects a continuous safety field—any hostile mobs that wander into your construction zone will immediately sprint away in terror.
- Holographic Forcefield: See exactly where your building limits are with a lag-free, highly visible holographic world border, complete with custom glowing boundaries on the ceiling and floor.
Dimensional Restriction: The Astral Building Nexus cannot be used in the Nether or the End.
