Why is it on some routes that I use this grass spline you can see the grass when you zoom way out as you can see here:

And some routes when you zoom out at the same distance the grass disappears as one can see here:

But when ya zoom into almost the tracks, the grass reappears as one can see here:

Any idea on what causes this??
