I am working on a game project where most of the action takes place in a large scene that is built to look like a space station. Because it is all technological and enclosed, I can't use a directional light to light the whole scene, and I need to be able to change the color of the lights for an alarm system. I can't bake the lights, because then I can't change their color, and I can't leave them all as dynamic lights, because I have about fifty spot-lights, and they take up a huge amount of memory, so much so that the lights can't even render on mobile devices.
Is there any way to do this without baking?
I am getting about 3000 batches in the Unity Editor Stats on average, in some places it is higher. Even viewing the game in full screen in the editor makes the game run super slow because of the amount of rendering it has to do, and I have a pretty new computer.
And here's the Stats box:
Here is an example of my scene in play mode:
UPDATE: I removed the shadow casting, which isn't necessary for my project, and it improved the framerate slightly, and the batches number is smaller, averaging out at about 1500 now, but the performance still is not optimal.
