Click in the world to place a procedural tree or rock; each click varies. Auto picks a species suited to the biome you click in. Trees grow up from the clicked block.

Click a cave floor to grow a stalagmite, or a ceiling to hang a stalactite — the face you click picks the direction, and Spike height sets how tall it grows (it stops short if the cave is smaller). Material chooses pointed dripstone, sulfur spikes or amethyst crystals. Spike base patch surrounds the root with matching stone.

Drag over terrain to paint biome-aware nature: grass, flowers, shrubs, ground detail — and whole forests with the Trees layer on. Auto species follows the biome under each column. With the Spikes layer on the brush also works underground: it finds the cave floor under the cursor and the ceiling over it and grows stalagmites and stalactites there, sometimes meeting in the middle as a full column. Spike base patch, on by default, replaces a little natural stone around each root — turn it off to leave terrain exactly as it was.

Drag to remove painted nature — only plants, shrubs and (with the Trees layer on) leaves & logs are cleared; terrain and builds stay. With the Spikes layer on, stalactites, stalagmites and amethyst crystals go too; the stone patch around their roots stays, since it's ordinary terrain.
