First of all, I wanna say that Bob's mods are amazing. If anyone ever modded he knows how much effort requires to make such complex modules as Bob's mods. Thanks you Bob
I've enjoyed playing with Bob's mods expanded Factorio for many hours, however, I always wanted to have a visual understanding of what tier of the structure I'm looking at. So I decided to create a small graphic addon to complement his work. Nothing fancy just some basic recoloring in order to be able to identify the tier of the building just by looking at it.
Steam-engines from Bob's Power
MK2 - yellow, MK3 - red. Similar to the original game.
MK2 - yellow, MK3 - red, MK4 - green. I didn't want them to appear fully painted but to have their paint almost completely fallen off except for the roof.
Pumpjacks from Bob's Mining
MK2 - yellow, MK3 - red, MK4 - blue, MK5 - white(I wanted to try something new)
MK2 - yellow, MK3 - red, MK4 - blue, MK5 - green
I also changed the default icon for the Drills, since the one that comes with Factorio looks nothing like the mining drill but rather as a fan or a transmitting station. I'm not very happy with my version either since I'm not big of a spiter, but I tried to create a drill from a mining drill.
I'll change area mining drill icons, since their "A" is covered with the digits which represents the number of items you are holding.
