What mobile needs
On a phone the enemies of vegetation are triangles, texture memory and overdraw from leaves. FoliMesh lets you control all three.
Low-poly style
Low-poly assets use flat shading and vertex colour — no textures at all — and only a few hundred triangles each.
Realistic, but lighter
For realistic trees, set lower triangle budgets per LOD and use leaf cards that cover the crown with less overdraw. The generator shows the overdraw before export.
Engines
Unity and Godot packages work on mobile out of the box; GLB keeps files small for web games too.
