Tracks with no shadows cast on white lines/road marking: Okutama for example

[Billy Pilgrim]

Hi
I've noticed this problem with a couple of tracks, most recently with the excellent-looking Okutama: the cars don't cast shadows on some of the road markings.

I've understood that this is because the road markings are slightly above the road (not actually on the road) and so the cars' shadows are under the road markings.

I've got this problem with Okutama, for example. Seems some people have the same problem as I do and others don't with this same track.

Can anyone help?

I'm using CSP 1.25 preview49 and CM
