The Shuriken looks like it was originaly made for asphalt but ended up bieng modified for offroad.
Including all available paint jobs from the game with their damaged version. The normal texture are originaly as “Object” space but also have been baked into a “Tangent” space version.
All right goes to Asobo Studio and Codermasters from their 2008 game FUEL.
