Virtuali,
I have the same exact issue this person has in P3D V4.
After installing, and prior to activating, the scenery looked as expected. And when P3D was running, and I clicked on the Pull-Down menu "Add-ons," the following were showing:
- SODE 1.5.3
- Couatl
- Addon Manager
However, after activating the scenery, the scenery degraded to the image shown at the top of this thread. Again, with P3D running, I clicked on "Add-ons," only the following were now showing:
- SODE 1.5.3
- Addon Manager
In the process of activation, the scenery changed and I lost Coutal pull down choice.
