Yes go to the bottom of the forum and get the P3D add -on version of Tongass..
Direct LiNK:
https://forum.mistymoorings.com/index.php?topic=5191.0Make sure you do the terrain.cfg entries correctly...
The correct terrain.cfg to edit is:
P3Dv4x - Terrain.cfg file is located in HIDDEN P3Dv4x sim folder:
C:\ProgramData\Lockheed Martin\Prepar3D v4.
P3Dv5x - Terrain.cfg file is located in HIDDEN P3Dv5x sim folder:
C:\ProgramData\Lockheed Martin\Prepar3D v5.
(If using the add-on Tongass, I have added the insertion point (or layers) which should be close enough to be in the correct location in the scenery order.
