TrainSim-Matt , Wouldn't Ray Tracing be nice for TSW? I have noticed a few errors or lighting which doesn't quite correspond to that in real life. Shadows where, really, there shouldn't be any (like on the gravel - that should be well illuminated as a stony but pale colour). During the day, there should be loads of light, even amounts that are blinding just like in reality. Some things appear too dark or too bright, or the wrong colour, or missing shadows, or shadows where there shouldn't be, or improper reflections, or unrealistic lights and pathological colours. The list continues, but ultimately the rasterised lighting and shading graphics are no longer good enough now that RTX 20 has arrived with its capabilities. The sun emits more light than UE4 would like to admit. Ray tracing isn't even a question. For those who can handle it and want it for extra graphical realism should be able to have it. Please add Ray Tracing to TSW.
