Explore the collection
Open Content/Examples/Maps/L_ProceduralPlant_Showcase in the example project. The refreshed map follows a winding gravel path through broadleaf trees, an orchard, conifers, understory planting, seasonal colour and a warm-climate collection.
| Collection | Examples |
|---|---|
| Broadleaf | Spreading oak, silver birch, copper beech and field maple. |
| Orchard | Apple, pear and wild cherry, with fruit included in the exported geometry. |
| Conifers and seasonal colour | Scots pine, Norway spruce, weeping willow and autumn maple. |
| Understory | Hazel, fruiting rosehip, ferns, green meadow grass and dry grass. |
| Warm climate | Banana, coconut palm, date palm and bamboo. |
| Roots and form | Veteran oak, five-stem birch, wind-bent pine, twisted olive, buttress fig, seven-stem willow, forked beech and a leafless branching study. |
Curved trunks and exposed roots
Eight additional recipes demonstrate trunk bends and elbows, unequal stem clusters, low forks and successive curved branch orders. Their root networks contain structural roots, lateral forks and finer roots as mesh geometry. Selected specimens replace upright trees along the main walk, with additional study positions and clear ground around the root collars.
The base temperate collection also includes tapered surface roots and short buttress flares. The example exporters join and remesh the lower trunk geometry, smooth the collars with a gradual falloff, weld them back to the upper trunk, and carry canopy and fruit through unchanged. Rounded buttresses replace sharp fins, and outer root tips descend into the soil. Projected bark colour, normals and surface detail keep a consistent scale across the roots, then blend into the original trunk mapping. Roots and trunks share bark with a gradual darker soil collar. The planting pass samples the actual landscape, follows its slope and buries each origin by 4 cm.
Open the commented graphs in Content/Examples/PlantGraphs/Arboretum. Trunk Spine controls stem count, height variation, lean, gnarl and kinks. Roots controls spread and surface shape; two Branch Level orders add the smaller roots. The example project's Tools/build_structural_plants.py builds this collection. Run ST.start_assets(), wait for completion, then ST.install() after importing the module as ST.
Edit a specimen
The source graphs live in Content/Examples/PlantGraphs/Arboretum. Adjust the branch hierarchy, leaf-card prototype, foliage density, fruit settings or Seed, then export the complete plant again. The custom temperate recipes include two baked seed variants. Their current showcase exports contain one geometry detail tier; add and tune an LOD Table before using them for a larger forest.
The example project's Tools/build_arboretum.py contains the recipes and staged scene-building helpers. The saved showcase opens directly; running the builder is only needed when rebuilding its content. Original leaf and ground texture sources are kept with the example assets.
