These licenses apply to the listed environment textures only, not to the album cover artwork from the user's collection. Architecture, window tracery, light shafts and ornaments are modeled in code in BDex; no third-party model is being claimed for those elements.

The detailed bronze chandeliers and sconces, leaded stained-glass patterns, glass grain, wax drips and metal surface grain are generated locally in BDex. No additional external asset or license is required for these additions.
