With OpenRails, the smoke of steam and diesel engines keeps the same illumination/color at night. When it makes use of a white or grey color, then it looks bright at night. This is not very realistic. Like precipitations, it should become darker.
This can be fixed by using the same shading method as rain drops and snow flakes. SVN patch is attached.
