We noticed that only very very few tracks were updated to RFE Plugin Series with the wetgroove (or drying line) texture that matches the requisites of its own track. Notwithstanding the effect is only a graphic one, you will agree that it is also very important for driving... this is the only way to see where put the wheels, how to handle an overtaking where the track is still partially wet and it is drying, in both cases we have a track that allows reflections or not. Only a drying line well done can give us a greater sense of immersion. For this reason we have updated the tutorial with more details about this important visual effect.
Thanks I didn't find the right solution from the Internet.
