The archive contains 3 preview images and 2 models in a single scene, one with textures and the other without textures. The preview texture is different as I imported the model to unity and apply different textures there.The file is in .FBX format and could be imported to Unity and Unreal Engine too (haven't tried it but should be possible).To apply textures, it is easy. You can apply textures to the grip as well as the blade of your choice. The one in the previews were already present in Unity, and you can even find better without spending money.If there is any problem, you can comment here)
