TimberGEN

TimberGEN is a fully custom, SpeedTree-style procedural tree generation system built natively for Unity. Design trees visually inside a single powerful editor window — tweak any parameter and see the result update live. Every tree is built from a hierarchy of generators (Trunk → Branches → Leaves, plus an optional imported root-flare mesh). Each generator can be driven by custom curves and transformed through a stack of non-destructive modifiers, so you can get from a rough silhouette to a final hero tree without ever rebuilding from scratch. TimberGEN ships with HDRP and URP shaders out of the box, a built-in billboard baker, automatic LOD generation, collision building, and a clean FBX export pipeline so your trees drop straight into any project — games, archviz, cinematics, or real-time environments. Whether you need a single hero tree or a full forest of variations, TimberGEN gives you complete artistic control with production-ready output.
