Snake Man,
Thank you for the link.
I am a bit confused by the statement, "When you are using addons properly as required Addons, you don't need to add files to your terrain dir or ask for permissions" as I have been following the PMC ArmA 3 Ultimate Terrain Tutorial guide in creating the above terrains. I was attempting to use standard Arma3 objects and similar structures like the RSO / PMC Opteryx Objects as part of these terrains.
