As I've noticed there is only a small amount of modern metal roofing in the game I'd thought I'd have a go at creating some with Distantz's Material editor. I whipped up a quick build of a Starbucks Drive Thru inspired Street Fox Coffee as test for them and I'm quite happy with the results. So far this pack has 1m,2m,4m Roof and 1m,2m,4m Gable Roof Pieces in this style. I may experiment with some additional textures later
