Following guide lines to the letter everything is ok except when trying to change from grass to tarmac or concrete also the vegetation doesn’t disappear from Polygon, all the necessary materials show in window and I can click and it shows in runway window but it doesn’t change from grass in the sim, I would be grateful for any advice as I’ve been trying all sorts of things for weeks now to no avail.
Did you find a solution?
I am having the exact same problem.
