Textures are mid quality for one model and low quality for other and there are no textures for normal and roughness. I used color texture for every segment , it works nice with blender but it might not work in other softwares. My model is exactly the same as in the preview images.You will not get the background materials, I used them in images for commercial purposes.If you like the background go check my model named : Call of Duty Modern Warfare Remastered Shipment Map.
You can also change the color of the barrels with my node setup.It is really good because you don't need new textures with other colors.This way you don't have to search for new textures and your computer will use less processing power.
