in the US Pits forum and in the Team Lightspeed N2002/N2003
Editing forum, someone said that copying the sky.3do from
/tracks/shared/shared.dat into the track directory of an Add-on
tracks cures the graphics problems.
This worked for me at the tracks where I've quickly tested it. The shadow
probs inside the***pit and the replay are gone. The ICR2 tracks still have
minor texture problems, but so far they seem to be of a less conspicuous
nature, on the trackside rather than in the middle of the drivers field of
vision. IMHO already quite well usable now.
Someone else said you also need the trkwin.stp from an original track, but
so far I couldn't see any diff with or without it.
