I can't seem to find the spline Relic uses in their maps.
The only texture that represents rail tracks is a very basic looking railroad track. I have tried opening Prypjat in WB but it didn't give me any information what kind of spline they were using. Only "no info"
It would be awesome as well if you could tell me how to implement railroad switches as well.
i forget exactly how to do this. but you double click on something, either the unit portait or the symbol in the top right (something like that) and the camera will follow that unit. you can then zoom in and rotate the camera around to have somewhat of a POV effect. i like doing this with tanks. makes it look like a completely different game.
