The capabilities that keep people paying for SpeedTree.
Procedural trunk, branch and leaf generators
Hand-editable generators for many species, with art-directed control over shape and variation.
Wind animation baked for engines
Automatic LODs and billboards
Engine and DCC export presets
Seasonal and species asset library
Wind animation data and LOD pipelines have to match each engine's vegetation shaders, and a useful species library needs many hours of botanical modeling.
Each covers part of the job. None replaces SpeedTree yet.
Partial: Geometry nodes and tree-generator add-ons build meshes; wind data, LODs and engine export are manual work.
List your tool on Gratistack when it works. Once an editor maps it to SpeedTree, it shows on this page and in search, and the people waiting here can hear about it.
