🌄 The world of Bent Bumper

The sky, the ground and the first props are photographs and scans from Poly Haven, all released under CC0 1.0: no attribution is required, and we give it anyway.

• The sky — "Kloofendal 48d Partly Cloudy (Pure Sky)" and "Qwantani Afternoon (Pure Sky)" and "Kloppenheim 06 (Pure Sky)", HDRIs by Greg Zaal and Dimitrios Savva, which also light every surface
• The ground — "Forrest Ground 01" and "Dense Sand"
• The road — "Dirt Aerial 02"
• Bark and rock — "Bark Brown 01" and "Rock Boulder Dry"
• The barrels — "Barrel 01"
• The asphalt stretches on the Bent Bumper circuits — "Asphalt 010" from ambientCG, also CC0 1.0

Loaded with three.js's HDRLoader and GLTFLoader (MIT, with three.js above).

🔧 The pit crew and their tools in Bent Bumper

The mechanics and the tools in the pit lane are models from Sketchfab, each released under CC BY 4.0. Their overalls are recoloured and carry the JUST mark; nothing else is changed.

• "car mechanic" by BELAZ
• "car_mechanic_girl_2" by tech.service.allwe
• "Mechanics Tool Chest with Top Box" by zeleniy89
• "Trolley Jack Lo Poly" by almartin

🧰 The garages in Bent Bumper

What stands in the six pit garages — the covered car, the lift, the cabinets, the tool cart, the oil drums and the small things — are models from Sketchfab, each released under CC BY 4.0. The two drums are modified: their oil-company labels are repainted with our own marks. The props pack is used in part, and one of its textures is edited to remove a slogan.

• "Garage Cabinets" by Victor_Biedrycki
• "Tool Cart" by jimbogies
• "Esso Barrel" by Bo Nicolaisen (labels repainted)

• "Marshals in W.obj" by Jakasan — the photographers on the pit balcony and the marshals at the wall (the pack split into its people)
• "Stadium Light" by thundermind — the masts down every track (the pole and arms from the pack, the lamp heads rebuilt simpler)
• "MTruck Toyota Baja" by Superfamicom — a monster truck (the wheels cut out of the pack's one mesh so they turn; the livery's makers' marks painted over)
• "ford mustang mach 1 monster truck", "chevrolet silverado 2500hd monster truck" and "gmc vandura monster truck" by amogusstrikesback2 — three more monster trucks (the makers' badges and lettering painted over, the van's stripes greyed so it takes a player's colour)

🚗 The cars in Bent Bumper

The cars are models from Sketchfab, each released under CC BY 4.0. Every car in the game is an invented marque: no real manufacturer's name, badge or shape is used.
