Hey Hunters 👋
You know the feeling: there's a castle in your head and a flat patch of grass in front of you. AI can draw that castle in seconds, but a picture can't be placed in a world. Block Dreamer is my attempt to close that gap.
What it does
You describe one structure in plain words, for example "a mossy stone castle with four round towers and a great hall", and get a Minecraft Java 1.21 build back. It opens in 3D, you can cut it at any height to look inside, and it comes with a layer plan and a block list counted in stacks.
What's special
• No mods needed. The default download is a vanilla .mcfunction: drop it in a datapack and one /function command places the build. The same build also comes as a .litematic and a .schem.
• Two ways to build. Classic writes buildings block by block, with rooms, stairs and furniture, at the size you ask for. Detailed 3D carves statues and creatures from a 3D model.
• Made for building by hand too. The layer plan and block list are there for survival players, and for Bedrock, where the files don't apply.
What it won't do
One structure per prompt: no cities, no terrain, no redstone. It can't build from an uploaded image yet. Detailed 3D builds are hollow shells, made to be looked at more than walked through.
Looking for feedback on
1. If you load the .litematic or .schem in your own setup, how did it go? Those files are the newest part.
2. Bedrock export, image input or bigger builds: which one would you want first?
Every build in the gallery is free to open, with its prompt, blocks and downloads, so you can look before you sign up. A free account starts with free credits.
Thanks for taking a look 🧱
