Grown, not modelled
The generator grows each tree from a skeleton: trunk flare, branch angles, the Leonardo thickness rule, sag under weight and age. That is why a realistic oak has the knotty crown of an oak and a pine has whorls of branches.
Bark and leaves
Trees come with bark and leaf textures and alpha-tested leaf cards. At distance the leaves switch to cheaper cards and finally to an impostor.
Age and shape
Set the age to get a sapling, a mature tree or an old giant with a raised crown and dead lower branches. Set a clear trunk height for forests where the hero sees trunks at eye level.
In your engine
GLB, FBX and OBJ plus packages for Unity, Unreal Engine and Godot.
