Metal Containers, it includes 3 different sizes, the most commonly found, i included the procedural material in two simple node groups that are easy to adjust to your liking, they can be baked into textures for better performance or use in a videogame, i also included the unaltered version with all its modifiers so you can easily make any other containter sizes.
I also included a universal .blend that has the containers without material and triangulated surface, they are ready to be exported in any other format that you need.
The procedural material can be a little hard on the CPU because of all the detail that is included.
The main reason of making a procedural material instead of having a texture is to have full controll over the different aspects of the material, maybe you want more rust or less, all of it can be manupulated within the node editor.
