So you’re saying the terrain is “fake” for much of the world in XP 12 where custom scenery isn’t used? Custom scenery typically covers a small percentage of the entire world. However, I want to be able to go to any random location in the world and I want the plane to react to the contours of the ground, including objects placed on the ground procedurally - I don’t want to rely on custom scenery for it. I just ran a test on MSFS 2024 in the desert in a random location that I picked:
The small boulder (or large rock) has been placed on the ground procedurally by MSFS 2024. You can see the left wheel of the XCub react to the small boulder (large rock) placed on the ground. And I can go to any random location in the world, and the XCub will behave like this to objects placed procedurally on the ground, although it seems the object needs to be of a specific size before the object has an impact. Note that I picked a random desert in the world, I didn’t install some custom scenery for this test beforehand, I just looked for a random desert with rocks and tested it.
Not having procedurally generated terrain for the entire world is a big minus when it comes to ground physics. That in my books, is a big minus for XP 12 and a big plus for MSFS 2024, if MSFS 2024 has procedurally generated terrain with rocks and boulders, and XP 12 does not and relies on custom scenery for it (because I can pick any random part of the world in MSFS 2024 and I know the ground physics will be good because of the procedurally generated terrain across the world).
