But the problem with TRS2019 lighting is the fact that it's near impossible to get a good mid-day lighting setup,although it is easier to do morning and evening lighting.
...As for differences,most of the T:ANE UI is very similar to the TS12 UI,but the TRS2019 UI was half-baked compared to the T:ANE UI to me,although it wasn't the worst. And the default TRS2019 lighting is horrid,and the default T:ANE lighting only really needed reduced fog. Although TurfFX was very nice,at the same time the UI for it wasn't very user-friendly,and PBR seems to mostly turn into unrealistically metallic reflections,even if it was a wooden trestle. And height-mapped textures are excellent when used correctly,but a lot of the textures have height differences to severe,or as in one of the built-in ballast textures,looked more like a bunch of eggshells right side up covered with dirt.
So,if you can master it,TRS2019 can possibly be better than T:ANE,but T:ANE's UI is much more user-friendly. I will admit,TRS2019 had much more potential than T:ANE,but N3V somehow messed up with the reflections and lighting,which I think almost blew it. So the decision is down to what the view of realism is.
No program is bug free,but old wood isn't metallic ether.
