The water in Tsw3 is actually a really good looking water texture to me, especially in training center. But on NYC - Trenton, the water texture resembles the water used in Tsw 2. If you look on Training center, you can see the reflection of the mountains, pier, and trains driving by and looks clear. But in NYC - Trenton you barely get any reflection or good looking texture. The texture looks very 2D and the pixels in the water are very noticeable, It looks very dated and old for a “new” route for TSW3. Feel free to compare the images below: TSW3 Training Center: TSW3 NYC- Trenton
There’s a good chance they might of just reused the water textures from NEC New York in TSW2020. Definitely needs an update!
