# Habitat scenery provenance

These are artistic digital-home props, not mapped vegetation, measured structures, or a surveyed depiction of an ecological site.

Changes: selected source meshes, removed unused binary attributes and mesh data, repacked glTF buffers. Display transforms normalize scale and arrange the props into new artistic habitats. Source files are preserved in `3d_assets`; rebuild using `python3 scripts/build-world-assets.py`. `attribution.json` retains author metadata, original URLs, and original/derived SHA-256 checksums.

The separately supplied Campfire model is CC BY-NC-SA and is **not included** in these exports. No supplied models contain character animation. The moving seed sprite is original procedural geometry and animation.

The world river asset is independent: USGS NHDPlus HR geographic centerlines published by the Front Range Bioregional Twin, clipped using `scripts/build-world-rivers.py`. Rendered width is cartographic. These static ribbons do not report measured flow, current water extent, or channel width. Regional terrain uses the approximately 400 m sampled Mapzen/AWS Terrarium grid. The Boulder Creek area replaces aligned cells with a 313×313 patch sampled at approximately 63–68 m from zoom 12 Terrarium tiles, blending to the regional surface along its edges. Source tile URLs and checksums are included in boulder-creek-dem.json. These are sampling densities, not claims of survey accuracy. Close-up props remain artistic.
