I have a Sci-Fi city model. It's entirely square and therefore very modular.
It has been multiplied many times to give me enough background for a fast dogfight between two craft. To try to disguise the obvious repetition I want to make the lights of each city section a different colour from each other. The emission node of the copied first section is controlling the colour of every duplicated section, however. Adding an emission to each individual section isn't working - the node setup of the original section overrides all the others.
This is where my inexperience is being exposed - but hey, it's why we have help forums!
Naturally, a fix for this one will be splendid!
