Adjust your lighting...
Go into Environment settings... in Surveyor.
Reset the lighting to remove any settings brought over from T:ANE. This will lighten up the scene for you.
Yes this is TRS2019 all adjusted with brighter lighting!
While in Surveyor, I also set my time to Noon so as to have my shadows overhead. It doesn't remove the shadows 100% but it's a lot better.
The track, however, is another issue. It has something to do with the textures. I unfortunately don't remember what the parameters are for the textures, but if you created the track yourself, you maybe able to fix that by adjusting the textures. If not maybe you can do it anyway. Hopefully someone comes along and can help you with this.
For your driving sessions, you can adjust the fog, sun brightness, and ambient light. Yes there are now these other two settings that are missing from T:ANE, and with some tweaking you can get the sunlight to be what you want.
