Downloads are unity packages. But includes fbx files too (if you need to use on other software).
Car models are very detailed and have ~250K poly each!
Models have textures on wheels, grilles, interior and lights!
Wheels and calipers are separated and have origin-pivots, so can be animated-changed etc. easily.
Steering wheels are separated and pivoted too!
WARNING: These individual packages contains only 3d model and its textures within a unity package scene (as seen on screenshots). No special shaders, effects, particles, lightning or other models (like background etc.) are included! If you want to get unique car shaders, decals, planar reflections, sounds, particle effects and more, you have to get the full packages here: Packages
