These are some of the best grass model i've seen in Terragen and Walli's a fantastic modeller. NWDA is becoming a great site with the tech packs, objects and tech articles available. It also seems Franks "recruited" some of the best guys around to provide stuff for the site so everything is of the highest quality.
Certainly going to order this grass and i'm also going to buy TU Canyon & Rock Surface Pack at the same time.
Great job guys.
