Motion Path and animation snapshot

[Anonymous]

Hello.

I am modeling a subway track and are making it using the motion path animation and animation snapshot option.

But my problem is with the curve that I'm creating the animation on is flipped(rotated) about half way through. See pic below.

What may cause this problem? (note: the polygon object is linear tangent in the graph editor.)

not sure what's wrong by your image. 

however, with motion paths it's always a good idea to use an 'up vector'  to tell the object on the path which direction "up" is. 

 and UP doesn't necc have to be positive Y axis ( granted in your case, that's prb what you should use )
