All my models are made as one whole object, without materials, without unwrapping, with a not too dense mesh. This is because, as my practice of selling 3D models shows, each designer himself will expose the materials he needs and what he likes best, and will also make a unwrap and bake textures if necessary. Accordingly, I set a low price, because I do not waste time and resources on additional work. As the main image in my products, a picture with an object's mesh is presented, I do this for a reason, I believe that in this way you must immediately see which mesh the object has and than decide whether the object is right for you and whether it is worth buying it. Most of my objects have been used in other projects, but this does not prevent you from using them for your own purposes. Hope you appreciate it and I wish you the best of luck with your projects. With respect to everyone!
