Treeplacer Mod Wiki & Guide

Create a configuration file in your mod's config folder, then define rules for how saplings should grow. The mod reads these rules when trees attempt to grow, so you can start customizing immediately without needing special items or crafting.

Yes, you can create separate rules for each sapling type and specify different tree structures for each one, even within the same biome. This lets you have oak, birch, and spruce saplings all grow into completely different custom trees in the same location.

You can use any solid block as a soil condition—dirt, grass, sand, stone, custom blocks, and more. This means you can make saplings grow different trees depending on whether they're planted on dirt versus sand versus other materials.

Define a custom tree structure in your configuration that specifies a 2×2 footprint, then assign that structure to a sapling rule. When four saplings are planted in a 2×2 pattern and the growth conditions are met, they'll grow into your custom large tree.
