Build Blueprint

---

Stop guessing. Start building.

Ever tried to copy a build from a picture or a video and lost count halfway through? Build Blueprint puts the whole build into your world as see-through ghost blocks. You place the real blocks right where the ghosts are, one layer at a time, until it’s done.

🔥 What it does

👻 See it before you build it
The full build appears as ghost blocks in your world. Move it, turn it, mirror it or drop it onto the ground until it’s exactly where you want it. Then press Delete to lock it in place.

🧱 Build layer by layer
Start at the bottom. The mod shows one layer at a time and moves you up when you finish it. If you break a block in a layer you already finished, it takes you back to fix it.

📋 Know exactly what you need
A live list shows every block the build needs, how many you have, and how many are left. Hover any block to see how many stacks you still need. Opened chests nearby that hold blocks you still need get a green glow.

🎯 Never lose your place
A pulsing box shows the next block to place. Middle-click any ghost block to put that block in your hand.

🎨 Make it yours
Click any block in the list and pick another one to use instead: any block in the game, even blocks from other mods you have. Search by name, or start with similar blocks (stairs stay stairs, closest colours first). Every block of that kind in the build changes, and Undo swap puts it back.

📸 Copy any build in your world/Other servers
Look at a corner of a build and press Insert. A box starts on that block: make it as big as the build with the arrow keys, or look at the far corner and press Page Down to stretch it there. Save it, share it as a code, or build it again somewhere else.

⚡ Creative mode extras
In Creative mode the mod can build it for you. Auto-build places the whole build at once, Build layer places just the layer you’re on, and Undo build takes it all back if you change your mind. On servers this needs operator rights.

💾 It remembers
Leave the world and come back, and your blueprint is still there, right where you left it.
