Wildgrove: Dynamic Forest, Trees & Vegetation (URP)

72 unique FBX models, each with LOD0, LOD1 and LOD2 (216 meshes).

82 prefabs: 72 model prefabs, 8 habitat assemblies and 2 particle effects.

2 demo scenes: woodland showcase and browsable asset gallery.

LOD0: 2–32,270 triangles per model; 648,247 across the unique library.

56 PNG textures. Exact dimensions and map names: TextureInventory.json.

Shared PBR sets: sRGB base color, linear tangent normal and metallic/smoothness (metallic R, smoothness A). Cutout alpha in foliage base colors. Water has a ripple normal. 2048 x 2048 surface textures; 1024 x 1024 foliage/ripple textures; 64 x 64 soft particle texture.

Source photographic albedos were generated at 1254 x 1254 and processed/resized. 2048 outputs do not imply native 2K captured detail. Surface normals are image/height-derived, not sculpt bakes. Tree foliage normals are flat texture maps combined with custom vertex normals.

Unity 6000.3.21f1 / URP 17.3.0 / linear color. URP Forward tested configuration. HDRP and Built-in implementations are not included.

1 Unity unit = 1 metre. Normalized prefab roots. Four 4 x 4 m ground modules and a 4 x 4 m water module have corner pivots.

Trees: approximate trunk capsules. Rocks: static LOD2 mesh colliders. Deadwood: approximate boxes. Small vegetation: no collision.

GPU wind and leaf flutter, color-based autumn transition, wetness, adjustable shafts, rain and pollen example effects. Three LODs and dither crossfade, expanded wind bounds.

Transparent pond water with depth tint, ripple normals, refraction and baked environment reflection. No buoyancy, water physics, flow simulation or dynamic planar reflection.

This is an environment art kit with demonstration scripts, not an ecosystem or terrain-authoring system. No terrain painting tools, seasonal leaf shedding, snow, animals, gameplay, player controller physics or inventory systems.

Use one active ForestEnvironment per loaded scene. No custom motion-vector pass: prefer MSAA/SMAA; TAA behavior is not certified. No mobile, VR, console, HDRP or Built-in performance/compatibility claim.

Demo profile: GPU instancing, SRP Batcher disabled, 2x MSAA, 2 x 2048 shadow cascades / 55 m, medium soft shadows, downsampled SSAO, LOD bias 1. Small ground cover does not cast shadows. Tune quality for your content and target hardware.

Rigging: No skeletal rigs. Animation clips: 0. Motion uses shader wind. UV mapping: Yes.

Revision 9 tree construction: smooth trunk/primary branch paths, volume union and rounded junctions, projected metre-scale bark UVs. Smaller twigs remain tube meshes. Foliage has mirrored, rolled and scaled clusters with coherent per-card wind phase. This is procedural geometry processing, not a sculpt bake.
