I posted a query on RD's forums to see if anyone else was having grass textures "growing" up through run off areas on Patrick Giranthon's Spa and Monza.
Spa had the worst of the 2 with grass poking up through run offs at Les Combes, No Name, Pouhon, Stavelot and the run down to Blanchimont.
Monza had the issue at the second Lesmo and on the left when braking for the Parabolica.
A couple of people came forward and confirmed they had these issues as well but we couldn't seem to come up with a fix until RD member @Reb.Ellion contacted me and came up with this fix.
Reb kindly gave me permission to upload his fix here
So, thank you Reb...you have calmed my OCD
Just extract to your Automobilista folder and if by magic, a well paid man will go out on track and mow the lawn for you.
If you do not have the problem, you do not need to install this fix.
