I downloaded some new pitcrew graphics and exported them to gp4 using CSC4, now however all the pitcrews are invisible! If i open CSC4 again and import pitcrews, the new updated are there , all present and correct. I try to export them again but to no avail.
this happened to me, so i adjusted the pitcrew settings in the graphics menu in game, then put it back to the setting that i wanted it to be on i.e the highest !.
this cured the problem for me give it a try.
i also tried the replacing f1 config trick but it didn't work 4 me !
