Blender 3d NURBS Path objects move I was trying to create train tracks using NURBS path and everything looks to be great till I press play.

As soon as I play it in Blender Game Engine, the objects are no longer merged and have a clear separation (making it unrealistic).

I believe the problem is that one of the object moves till it reaches the other ones edges, but what I want is that they should not realign themselves.

Here is the blend file.
It finally worked! I was trying to recalculate normals of the base but I was not recalculating for the tracks which were being duplicated. So the steps are the same for all objects and related objects to the curve
