Free McLaren P1 GTR by ALIEEEN, formerly Desiccated_Lemon.
Free Koenigsegg Gemera by ALIEEEN, formerly Desiccated_Lemon. This model depicts the original TFG concept.
Lamborghini Aventador by BlackCube, based on Aventador SVJ Black-Ghost by SDC / 3Duae. Both sources are CC BY 4.0. Includes the author's custom body kit.
Models were scaled and aligned to the game, wheels separated for steering and suspension, brake discs separated from calipers, and paint, glass and lights adapted for WebGPU. Original model geometry and source textures are retained. Mobile copies use textures resized to at most 512 pixels; surface textures and sky panoramas also have smaller Low and Medium variants. Runtime geometry detail scales with quality and distance. Performance values are tuned for gameplay.
Asphalt Track and Seaside Rock by Dimitrios Savva; Concrete Wall 003 photographed by Dimitrios Savva and processed by Rico Cilliers; Rock Face 01 by Dario Barresi. Surface textures are used at 2K with physical repeat scales; the rock model retains its geometry and 1K maps.
Kloofendal 48d Partly Cloudy (Pure Sky) by Greg Zaal and Jarod Guest. A 2K HDR panorama, adapted for lighting, weather and day/night transitions. All these assets use CC0 1.0; see Poly Haven licensing.
Ocean waves at Lækjavik beach, Iceland by Alexander Grebenkov, CC BY 3.0. Changes: audio extracted, high-pass filtered, crossfaded into a loop and encoded as Opus. Played on the coastal circuit.
Car peels off by therisingorder, CC0 1.0. Recorded tyre skid; the public HQ MP3 preview is trimmed, filtered, crossfaded and encoded as Opus. This is a tyre sound, not a recording of any specific garage car's engine.
Alternative car distribution: Objaverse by the Allen Institute for AI, whose individual asset records retain their original licenses. Five cars and the circuit layouts remain procedural. Engine audio remains synthesized; complete recordings of the exact engines have not been integrated.
