So, this is a very simple request, but it would be nice if headlight flares were more in tune with how they look like in real life and not these blinding white circles.
Aren't these textures with an alpha channel? Look for them in the light emitter bins and try swapping them for another that is more to your liking?
The Acela is probably the best example I can think of when it comes to the headlights. I personally think Dovetail did a good job with the front headlights and how they look.
Lol, are you kidding me! Look at the above comparison shots. The headlight flares on US freight locomotives seriously need to be fixed. Great suggestion Blacknred81!
