TreeGenerator Importer brings assets created in Tree Generator into Unreal Engine and Unity with focused, production-friendly import workflows.

Import Tree Generator .glb exports with materials, textures, custom collision, LODs, wind/growth material setup, and organized project folders. Unreal Engine imports also support optional Nanite setup, and the Unreal Engine 5.7 version includes Tree Generator MegaPlants package import for creating compatible Procedural Vegetation assets, presets, palette meshes, growth paths, and graph setup for Unreal’s MegaPlants workflow.

For Unity, the package includes importer files, runtime growth support, a prefab setup, and wind shaders for Built-in Render Pipeline, URP, and HDRP.

Dependencies Unreal:
This plugin uses Unreal Engine’s Interchange plugin for Tree Generator GLB import. The Unreal Engine 5.7 MegaPlants importer also requires PCG and ProceduralVegetationEditor, which are enabled by the plugin for MegaPlants graph and Procedural Vegetation asset creation.
