ROOM CIRCUIT — asset credits

Vehicle design, livery, room composition, interface, procedural audio and the main authored geometry were created for this project.
Licensed source meshes and materials are listed below.
No real motorsport team, sponsor or vehicle manufacturer marks are used.

Wooden Floor 02 — Charlotte Baglioni (scanning), Rico Cilliers (processing), Poly Haven.
https://polyhaven.com/a/wooden_floor_02
Oak Veneer 03 — Jenelle van Heerden, Poly Haven.
https://polyhaven.com/a/oak_veneer_03
Both source asset pages list CC0. Local 1K color, OpenGL normal and roughness maps are included.
Source download URLs and MD5 verification are recorded in artifacts/texture-sources.json in the source project.

Three.js — MIT, https://github.com/mrdoob/three.js
Rapier — Apache-2.0, https://github.com/dimforge/rapier.js

Throw Pillows 01 — Serhii Khromov, Poly Haven.
https://polyhaven.com/a/throw_pillows_01
CC0. Source scan geometry, UVs, normal and roughness maps retained; dimensions, orientation and white/ochre fabric colors adapted for the bedroom.

Potted Plant 02 — Rico Cilliers, Poly Haven.
https://polyhaven.com/a/potted_plant_02
CC0. Leaf and pot geometry retained. Soil mesh simplified from 53,930 to 647 triangles; complete model 16,523 triangles. Local 1K maps included.
Small raceway planting LOD: original local scan reduced to 2,185 triangles (soil64/leaves1,603/pot518); geometry and UV only, shares those same local maps. Generator: tools/create-track-plant-lod.py.

Source URLs, original MD5 checks, dimensions and derived asset hashes are recorded in artifacts/asset-candidates/ in the source project.

Draped indigo duvet — original baked Blender Cloth simulation for this project.
Generator, local bounds and collision audit: tools/build-duvet.py and artifacts/duvet/.

Denim Fabric 06 — Greg Zaal (photography), Rico Cilliers (processing), Poly Haven.
https://polyhaven.com/a/denim_fabric_06
License: CC0, https://polyhaven.com/license
Duvet surface: unmodified local 1K diffuse, OpenGL normal and roughness scans.
Material tint preserves the previous duvet's mean linear diffuse colour; the
original approximately 25.4 cm scan scale is retained. No source image is used
as scene geometry or a background. Source API metadata, URLs and verified MD5
checksums: artifacts/duvet-weave-final/ in the source project.

Asphalt Track PBR textures — Dimitrios Savva / Poly Haven
Source: https://polyhaven.com/a/asphalt_track
License: CC0 1.0, https://polyhaven.com/license
Bundled: 1K diffuse, OpenGL normal, roughness. Original scan spans 2 metres.
Download URLs, MD5 verification and original metadata are retained in
artifacts/asset-candidates/asphalt_track/ in the source project.

Laminate Floor 02 — Charlotte Baglioni (photography), Dario Barresi (processing), Poly Haven.
https://polyhaven.com/a/laminate_floor_02
CC0. Active bedroom floor: local 1K color, OpenGL normal and roughness maps, tiled at the source physical scale of 1.7m.
Previous Wooden Floor 02 files are preserved as a comparison candidate. Source checksums: artifacts/asset-candidates/floor/laminate_floor_02/integrated-manifest.json.

Historical racing-engine recording (retained, not used by the current engine):
JosVtpMin.aif — Heigh-hoo, Freesound #14828
https://freesound.org/people/Heigh-hoo/sounds/14828/
CC0 1.0: https://creativecommons.org/publicdomain/zero/1.0/
Author describes a 2003 Suzuka Minardi PS03/Cosworth CR-3 trackside recording.
Source: public high-quality MP3 preview; excerpted, mono-converted, loudness-leveled and crossfaded for a continuous RPM-controlled loop.
This is a processed real recording, not an official/team-licensed sound pack or an onboard multi-RPM library.
Historical file: audio/historical-engine-track-loop.wav — current engine does not load or play it.
No purchase or paid generation was used.

Modern formula audio revision (2026-10-24):
The current engine uses five edited layers of a real V8 engine-compartment take:
ferrari355underhood4.mp3 — enginemusic (Matt), Freesound #43484.
https://freesound.org/people/enginemusic/sounds/43484/
CC BY 3.0: https://creativecommons.org/licenses/by/3.0/
Selected same-take speed/load/coast regions; stereo downmix, DC removal,
crossfaded loops, filtering and level normalization. Eight game audio gears,
load crossfades and bounded playback-rate adjustment control the samples.
This is not a modern formula race recording. The legacy synthesis API remains for old callers,
but is silent when the active game requests the recorded V8 manifest.
It does not fetch or play the historical trackside loop above.
No official/team/video sound was copied and no paid service was used.
See licenses/MODERN-FORMULA-AUDIO.txt for factual references and sourcing limits.


ENGLISH RACE RADIO — LOCAL SYNTHETIC VOICE
Kokoro-82M v1.0 / bm_george (hexgrad), Apache-2.0 weights.
https://huggingface.co/hexgrad/Kokoro-82M
Generated locally using kokoro-onnx (MIT); no paid/remote TTS.
Original anonymous engineer phrases, light radio filtering; NOT human recordings
or a real race driver/engineer imitation. See licenses/RADIO-VOICE.txt.
PTT opening/closing noise and low speech-period hiss are original offline DSP
effects added for this game, not extracted team-radio or television audio.

2026-10-24: Mini Formula radio v3 adds an original 60ms / 1450Hz call tone,
40ms opening static, speech-floor hiss at -24dB relative to the voice, and
32ms end squelch. Generated locally, no broadcast recordings reused.
