I've always wondered why in TSW, we don't have proper shaders for the passenger interior area of trains? For those that don't know what this is, its basically shadows, such as shadows under seats. This isn't just limited to seats, but also areas which will naturally cast a shadow. Why is this important? It makes things look a whole less flat and bland. Something which, unfortunately, is an issue in TSW. I understand that there could be some performance issues with having shadows under every single seat, but surely you can have some sort of 'static' shadow, which would be better than no shadow at all? Below highlights the issue. It looks like the seats aren't even connected to the interior. For comparison, this is what is possible in TS1. Just look at how much more realistic and less flat looking the interior looks.
