I've also tried with Talladega and some original tracks - no visor!
Downloaded the NASCAR2015 mod without deleting anything... no visor
No visor-tex found in the mod...
Could anyone tell me please how this visor feature works?
Until now I managed it that way: I updated the track folders with the visor-folder containing visorlower.tex, visorupper00 to visorupper11.tex and it worked allright.
There's also a Visor-folder in GRAND PRIX/MAPS/RESOURCES/Visor but apperently it has no effects...
So what to do?
