Catching up with the discussion and like CT I have bridges on my radar.
Thank you all for your contributions.
One thing I would like to do is traffic-able raised ramps for trains. There are quite a few around Leningrad, in marshy-swampy areas in particular.
This would also add some depth to the rail tracks (for them to stand out and project shadows like so:
The almost vertical rail line is the Oktyabrskaya, three track-wide here, linking Leningrad and Moscow. It has 2 single tracks, on ramp, cutting it (one straight, one curved).
Now time to dive into 3DMax, I am getting ok with 2D plates... bring on 3D!
For hitboxes we may have to put them on the side of the bridge platform? So you send your bombs/rockets just to the side and you get 10 points!
