A shallow fill spline made of grass, but with no endcaps for better alignment to objects such as bridge abutments.
For use under track (align the spline points with the spline points of the track).
This can also be used as a road if no track is used.
Fits narrow gauge track.
Textures courtesy of CGTextures.
A little more desaturated than the grass version to better match some of the grass ground textures out there.
Revision 1: added seasonal support.
