Accepted scene library inputs

birch.glb is derived from BirchTree_1 in Quaternius’s Ultimate Stylized Nature Pack. Source, original and derived hashes, modifications and the CC0 license are recorded in provenance.json and Quaternius-LICENSE.txt. The source license’s reused pack title is preserved with line endings normalized; the official nature-pack page independently marks the files CC0.

Supply the original glTF, bin and three textures to node tools/planet-nature.mjs <folder>. The importer normalizes the foot and height, changes transparent leaves to alpha cutouts, then uses the repository’s pinned glTF optimization path. A changed result cannot overwrite the accepted file: review a new version/file and loader mapping. No generation or download runs.

This is environmental vegetation with a narrow trunk footprint, not an interactive asset or an assertion that all source-pack assets match the house style. Several scene trees share the one downloaded/parsed model. Required vegetation loads before reveal; failure shows a retry message instead of silently revealing a primitive replacement.
