FOOTBALL GEOMETRY & SURFACES — Gameplay Football / Unlicense
Original author: Bastiaan Konings Schuiling, Gameplay Football; distributed in Google Research Football's third_party/gfootball_engine subtree.
Primary source: https://github.com/google-research/football/tree/master/third_party/gfootball_engine
Licence: https://raw.githubusercontent.com/google-research/football/master/third_party/gfootball_engine/LICENSE
A copy of the Unlicense is included at football/LICENSE.txt. No C++ engine or proprietary Four Corners application code is included.
football/goal.json: independently converted from data/media/objects/stadiums/goals.ase. One goal extracted; duplicate reverse net faces omitted; axes converted to Y-up; normals computed. Runtime scales goal size and depth.
football/ball.json and ball.png: independently converted from objects/balls/generic.ase and ball.bmp. Geometry normalized to radius1, axes converted, UVs preserved, smooth radial normals computed. Original white/lime skin retained; this is not claimed to be Four Corners' exact ball skin.
football/grass.jpg: textures/pitch/seamlessgrass08.bmp, JPEG encoding.
football/concrete.jpg and concrete-normal.png: textures/concrete/concrete.wall01a.bmp and concrete.wall01_normal.bmp, JPEG/PNG encoding.
football/netting.png: textures/stadium/goalnetting.bmp, RGBA PNG preserving transparency.
Four Corners' public bundle identifies the same upstream asset family. These files were obtained from the independent original distribution and converted for this game, not copied from Four Corners' customized exports. The existing independently licensed MakeHuman-derived people remain in use.

Version 4.5: the CC0 African menu instrumental remains unchanged. Original
street/crowd recordings and sound effects are retained; AMB Outside 1 is excluded
from preload/playback to remove the continuous hissing bed. New Stay event cues
reuse the credited Kenney impacts, with no synthesized background replacement.

Mobile variants (v4.7): resized photographic surfaces and embedded character textures derived from the corresponding licensed assets above. Character meshes and animations are unchanged. Original licence terms apply.

AMPE WOMEN CHARACTER SHAPES (v4.14)
Female body, garment and hair morphs extracted from the existing CC0 generated
kblood/CharacterCreator output. Source and generated-file licence:
https://github.com/kblood/CharacterCreator/tree/master/output
https://github.com/kblood/CharacterCreator/blob/master/LICENSE-NOTES.md#generated-files-owner-decision-2026-10-03
The shape data reuses the existing character textures, skeleton and animations.
Extraction: scripts/build-female-shape.py. Clap/jump choreography is original.

Reward cues — 1 November 2026
assets/audio/rewards/{goal-fanfare,wood-point,rhythm-point,discovery-point,victory,ready}.mp3
Original procedural music/percussion created for Ghana Street Games using scripts/build-reward-audio.py. No external recordings or samples. Generated from pitched oscillators and decaying drum tones; no continuous noise layer. These replace applause and celebration claps. Physical Ampe/rhythm claps retain their existing credit above.

4.17 scene finishing: procedural court patina, markings, baked building shadows,
kit shader accents and additional street props are original Ghana Street Games
project artwork. Preview images are renders of this project's own game scenes.
No Four Corners GH proprietary artwork or source was imported for this art pass.
