In Train Simulator, the shadows feel too bright; they look like a light gray. I want them to be a dark gray, almost black. I tried adjusting the ambient light levels, but that just darkens everything. Is there any mod or texture pack that can help me achieve what I want without darkening the whole scene?
I would have thought that your best bet would be to adjust the contrast rather than ambient light, although maybe you tried that. Of course adjusting the contrast would make all dark objects darker but not the lighter objects.
