Wow man… That is it!!! Solved.
Gotta say though, I really had no idea where to look when you were talking about the obscuration layer… You learn something new every day, huh!
Whilst on my search for this setting, Google also revealed this amazingly simple tutorial, which is exactly what I needed, but as usual, sometimes it is incredibly difficult to find a simple and solid answer if you don’t type in the right keywords. (‘Obscuration’ is what helped!)

Why this never came up in my searches this morning I do not know.
Anyway; I really hope this helps people with the same question! Thanks for your speedy help, Kevin.
