This week I colored one of the two chute station models, a process that was made much easier once I remembered to apply the mesh modifiers so that I could select specific pieces of the model using Ctrl+L. I had to resize some textures again to get them to fit properly, but as you can see in the following image, it all worked out in the end:
Right now I'm working on coloring the other two buildings (there's three of this type in total, but the view I rendered from doesn't show them all at the moment); when I'm done with those, I'll move on to the remaining type of chute station.
