I use a bunch of vacuformed scenery my self. Put plenty of acrylic paint on it, both on the outer surfaces & on the inside to stiffen it up. be careful how you store it. Doesn't stack well because it can crush easily. I often use the vacuformed toy packaging too, look for shapes that make good hills & other obsticales. It is much lighter than other forms of scenery so just be careful in handling & storing & it works great.
