Thanks, Superku. I'm not only open to, but I always appreciate new ideas.
But you see, it's hard to follow your sig in my case .
I'm making a RTS game and I took into account about all the "terms" that would make the balance between visual richness and video load. I assumed like 500 objects simultaneously rendered, out of which 250 are tanks (a tank would be made out of ~5). This would be a peak, but encountered often. So I need to reduce the polys accordingly and still get the 3D feeling for the tracks (not to mention the animation...). I can't afford more objects in a tank.
And about the faulty use of the shader -- although I'm so tempted to do it, I'm not that rude to ask you for help once again. You already helped me once with an external topic But believe me, I'm disappointed about the parallax.
