Downloaded the master, I see the lights now. Oh well. But I'll still keep my texture map, I like the density of the cities.
BTW, I also reduced all the heightmap and normal maps of the mod by 1/4 to see how much of an impact it would have visually and on my hardware. It reduced my RAM load by 2GB and as far as I see there's been no decrease in visual fidelity. Because the color texture is so big, and most of the detail is actually stored there, reducing other textures doesn't really leave a noticeable drop in quality. Might be useful for those struggling with RAM usage like I was.
