Hi all can anyone tell me how I can have multiple grip levels for my track. What I am wanting is so that each section of the surface across the width of the track has it's own level. I understand that the tdf file is where I set up how I would like to set the settings for a particular name e.g. Roads or Poads Pits etc to the desired grip level. What I don't understand is how I assign these to a piece of track. Any help as always would be greatly appreciated.
