I am fairly sure factories or power generators don't actually point anywhere. Units do but i don't think many structures do, and being able to rotate the camera 360 degrees i forsee a lot of the time looking at units being upside. Maybe pointing north?
Factories have to know where the units they produce should go out, so I think they point to something in a way or another.
Yup, rotating icons would be a great addition to all units. Maybe the Tech 2 radar can detect the orientation of the blips it finds?
This is a neat idea, but I think they need to and will redo the strat icons first. Hoping they'll get some love in beta. They are "not optimal" right now, but I am very glad that I could make my own icons. Happy about how easy to mod this thing is.
Would be much harder to read unit composition and such quickly since you'd have to rotate symbols in your head.
