Each box has 2 sets of textures, new and old with signs of wear, which are compatible with each other, mixing them you can get additional varied variations, which can be useful when filling large areas. The boxes have an interior, the inner surface is also well elaborated, the lid is made as a separate object, it can be opened.
The color of the awning is very easy to change in the material settings, while all the textures of the details are completely preserved.
Labels and stickers are made as separate objects (decals), they can be moved, changed color or hidden if they are not needed. There are also 2 types of decals, new and wear.
All models consist only of quad polygons and support subdivision, for closeups you can use the turbosmooth or opensubdiv modifier.
