I never liked the textures of Steve's Factory Manager, so I decided to do a retexture of it...
I first tried staying at the default 16x textures, but soon realized that they won't allow me to do fine details in some places (like the GUI).
Because of that I decided to do 16x Hypertexturing, basically a 16x texture scaled up to 32x that still looks like 16x but allows some details to go in.
My inspiration for this was CyanideX's Unity resourcepack.
Here are some pictures:
