I don't do any editing. I just get those from a friend (read the whole post above) and I race. That is it.
Anyway, it is the same scenario as last year. I got the edited cars.wad and graphics.cfg, backed up and overwritten the old one and off to race using GPxPatch.
And I got the same error as last time. Some cars to completely white. Some do, some don't. Been checking around for possible solutions and tried them, they did not work.
As mentioned earlier, it was probably due to me not using lod0 but my friend who actually does so (smoglessbutton4).
