I just recently captured the Boathouse control point in the DLC and I was trying to spot stuff with my scope and photo mode. Then southwest of the control point I spotted two Black Tusk hovercraft in the distance. The rest of the background stuff was in 2d, but I can clearly see that the hovercrafts is 3d and has details on it. Just thought I'd share this.
