Hey! and there! My name is Luiz Eduardo and I make my 3D objects with few polygons, lowpoly objects for games.
I usually do them in the Blender 3D program, I do them in a way that makes it possible to apply generic animations. For example: These cars are set up for you to do wheel and steering animations. In total there are 7 cars with 6 seats each.
Furthermore, inside the zipped file is the original 3d model made in Blender 3D with its .blend extension, and it also comes with the following extra extensions: .fbx, (.gltf,.glb) and .obj.
I hope you enjoy it and create great low poly game projects.
