# Live 3D environment assets Local assets used by the realtime renderer (Rust/wgpu, `engine/`). Everything here is [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/) from [Poly Haven](https://polyhaven.com); the game never contacts Poly Haven at runtime. - `materials/` — PBR texture sets (albedo, OpenGL normal, roughness, displacement) packed at load time into one 22-layer texture array used by terrain, roads, buildings and props. Built by `scripts/import-materials.mjs` (layers 0–3 by `scripts/import-environment.mjs`). - `models/` — trees, shrubs, rocks and plants as GLB, each with a near (`name.glb`) and a far (`name-low.glb`) level of detail produced with meshoptimizer; textures re-encoded as 1024 px WebP. Built by `scripts/import-vegetation.mjs` and `scripts/import-environment.mjs`. Roadside trees draw the low LOD (broadleaf crowns rebuilt at load by thinning whole leaves of the near mesh); impostors with albedo and crown normals are baked from the near meshes at runtime. ## Sources | Asset | Poly Haven source | Authors | | ------------------------------------------ | ------------------------------------------------------------------------------------ | -------------------------------------------- | | Asphalt 02 | [asphalt_02](https://polyhaven.com/a/asphalt_02) | Rob Tuytel | | Leafy Grass | [leafy_grass](https://polyhaven.com/a/leafy_grass) | Charlotte Baglioni | | Gravel Road | [gravel_road](https://polyhaven.com/a/gravel_road) | Amal Kumar | | Rock Face 03 | [rock_face_03](https://polyhaven.com/a/rock_face_03) | Dario Barresi, Rico Cilliers | | Pine Sapling Small | [pine_sapling_small](https://polyhaven.com/a/pine_sapling_small) | Rob Tuytel, Rico Cilliers | | Fir Sapling | [fir_sapling](https://polyhaven.com/a/fir_sapling) | Rob Tuytel, Rico Cilliers | | Boulder 01 | [boulder_01](https://polyhaven.com/a/boulder_01) | Rico Cilliers | | Rock Face 01 | [rock_face_01](https://polyhaven.com/a/rock_face_01) | Dario Barresi | | Pine Tree 01 | [pine_tree_01](https://polyhaven.com/a/pine_tree_01) | Rob Tuytel, Rico Cilliers | | Rosendal Mountain Midmorning | [rosendal_mountain_midmorning](https://polyhaven.com/a/rosendal_mountain_midmorning) | Dimitrios Savva, Jarod Guest | | Jacaranda Tree | [jacaranda_tree](https://polyhaven.com/a/jacaranda_tree) | Rob Tuytel, Rico Cilliers | | Island Tree 02 | [island_tree_02](https://polyhaven.com/a/island_tree_02) | Rob Tuytel, Rico Cilliers | | Tree Small 02 | [tree_small_02](https://polyhaven.com/a/tree_small_02) | Rico Cilliers | | Shrub 02 | [shrub_02](https://polyhaven.com/a/shrub_02) | Rico Cilliers | | Shrub 03 | [shrub_03](https://polyhaven.com/a/shrub_03) | Rico Cilliers | | Shrub 04 | [shrub_04](https://polyhaven.com/a/shrub_04) | Rico Cilliers | | Quiver Tree 01 | [quiver_tree_01](https://polyhaven.com/a/quiver_tree_01) | James Ray Cock, Dario Barresi, Rico Cilliers | | Wild Rooibos Bush | [wild_rooibos_bush](https://polyhaven.com/a/wild_rooibos_bush) | James Ray Cock, Jenelle van Heerden | | Dead Tree Trunk 02 | [dead_tree_trunk_02](https://polyhaven.com/a/dead_tree_trunk_02) | Jenelle van Heerden, Rico Cilliers | | Fern 02 | [fern_02](https://polyhaven.com/a/fern_02) | Rob Tuytel, Rico Cilliers | | Namaqualand Boulder 02 | [namaqualand_boulder_02](https://polyhaven.com/a/namaqualand_boulder_02) | Greg Zaal, Rico Cilliers | | Street Lamp 01 | [street_lamp_01](https://polyhaven.com/a/street_lamp_01) | Josh Dean | | Snow 02 (material `snow`) | [snow_02](https://polyhaven.com/a/snow_02) | Rob Tuytel | | Coast Sand 01 (material `sand`) | [coast_sand_01](https://polyhaven.com/a/coast_sand_01) | Rob Tuytel | | Forest Floor (material `forest`) | [forest_floor](https://polyhaven.com/a/forest_floor) | eye-candy.xyz | | Farm Furrows (material `soil`) | [farm_furrows](https://polyhaven.com/a/farm_furrows) | Amal Kumar | | Dirt (material `dirt`) | [dirt](https://polyhaven.com/a/dirt) | Charlotte Baglioni | | Cobblestone 01 (material `cobble`) | [cobblestone_01](https://polyhaven.com/a/cobblestone_01) | Rob Tuytel | | Rectangular Paving (material `paving`) | [rectangular_paving](https://polyhaven.com/a/rectangular_paving) | Dimitrios Savva | | Dark Rock (material `darkrock`) | [dark_rock](https://polyhaven.com/a/dark_rock) | Amal Kumar | | Brown Mud 02 (material `mud`) | [brown_mud_02](https://polyhaven.com/a/brown_mud_02) | Rob Tuytel | | Dry Ground 01 (material `drygrass`) | [dry_ground_01](https://polyhaven.com/a/dry_ground_01) | Rob Tuytel | | Concrete Wall 008 (material `concrete`) | [concrete_wall_008](https://polyhaven.com/a/concrete_wall_008) | Dario Barresi, Charlotte Baglioni | | White Stucco 02 (material `plaster`) | [white_stucco_02](https://polyhaven.com/a/white_stucco_02) | Dimitrios Savva | | Red Brick (material `brick`) | [red_brick](https://polyhaven.com/a/red_brick) | Rob Tuytel | | Clay Roof Tiles (material `roofclay`) | [clay_roof_tiles](https://polyhaven.com/a/clay_roof_tiles) | Amal Kumar | | Grey Roof Tiles (material `roofslate`) | [grey_roof_tiles](https://polyhaven.com/a/grey_roof_tiles) | Rob Tuytel | | Weathered Plank Siding (material `wood`) | [weathered_plank_siding](https://polyhaven.com/a/weathered_plank_siding) | Dimitrios Savva | | Box Profile Metal Sheet (material `metal`) | [box_profile_metal_sheet](https://polyhaven.com/a/box_profile_metal_sheet) | Amal Kumar | | Old Stone Wall (material `stonewall`) | [old_stone_wall](https://polyhaven.com/a/old_stone_wall) | Charlotte Baglioni |
