Trees and Wood: Overview

Most BYG trees come as a wood set: a family of blocks made from one kind of log. The Wood Sets page lists every family and which blocks it has.

Turning a set off

Every set has an on/off option under Content Settings in the BYG config. Turning one off removes its blocks, items, recipes and world generation together with its biome content. It needs a Minecraft restart, and it should only be changed before you create a world, or blocks already placed will go missing.
