Minecraft Custom Tree Generator
Create custom trees with a real-time isometric preview. Choose the wood type, canopy shape, trunk height and thickness, and leaf density. Every tree has a touch of organic randomness — generate as many variations as you want with the same style, and export /fill, /setblock commands, a .mcfunction file, or a complete datapack.

In-game: /reload then /function crazyozz:tree_crazyozz.
The datapack already includes a README file with the full step-by-step, in case you'd rather set it up manually.

Choose the wood type and canopy shape, adjust the dimensions, and watch the isometric preview update in real time. Since the canopy uses a bit of randomness to look more natural, use "New variation" to generate another tree with exactly the same parameters. Once you like the result, export the commands, the function, or the complete datapack.
About the Canopy Shapes
Oak (irregular)
Organic, asymmetric canopy with irregular edges — the classic Minecraft oak look.
Spherical
Rounder, more uniform canopy without as much edge variation.
Conical (pine)
Decreasing layers forming a cone, resembling pine and Christmas trees.
Palm
Leaves concentrated only at the top of the trunk, spreading outward like fronds.
Frequently Asked Questions
Are the generated trees always the same?
No. The canopy is generated with a bit of randomness to look more natural. Use the "New variation" button to generate another tree with the same parameters.
What's the difference between the canopy shapes?
Oak (irregular) creates an organic, asymmetric canopy. Spherical is rounder and more uniform. Conical looks like a pine tree, narrowing toward the top. Palm creates leaves only at the top, spreading outward.
Why does the trunk turn into just one /fill command?
The trunk is always a solid, uniform box, so a single /fill box is enough to fill it entirely, no matter the chosen height or thickness.
Can I use any Minecraft wood type?
The generator includes all 8 wood types in the game: Oak, Birch, Spruce, Jungle, Acacia, Dark Oak, Cherry, and Mangrove.
