Oh The Trees You'll Grow: Building Custom Trees from Structure Templates

Turning Structure Templates into Trees

Oh The Trees You'll Grow lets you build trees in-game instead of writing generator code. You design a tree as a structure template file, then the mod uses it for world generation or sapling growth.

Tree models are split into separate trunk and canopy templates, so you can mix and match parts for modular combinations. Marker blocks inside the templates tell the mod where to place leaves, logs, and special features at precise locations.

During growth and generation, the mod handles random rotations, hanging vines, fruit placement, and block collision rules. Because it works entirely on the server side and adds no new items or blocks, it fits into existing worlds without extra content. Builders can save a template, mark it up, and let the mod grow it naturally across biomes.
