I downloaded and installed this file but the mountain images appear blurry. Is this normal?
No, the images are not displayed for you. The elevation mesh, on the other hand, looks fine.
Are you also on Beta? Can you turn it temporarly off?
SkywayTheDelta just informed me, that he can bypass the beta mode with the scenery downloaded offline and that it works very well now also for him.
The content is therefore only for the Official Version, I will specify this accordingly.
