Ok, maybe I'm using your script in the wrong way.
I did a comparison between Google Maps and what I get with my settings.
I've attached a picture.
My goal would not to have the very best map quality (indeed Google Maps is not so "high res") but to have quite a good quality, a large horizon and, if possible, not too much difference between the Map and the horizon (just like with Google Maps), regardless of the zoom level.
Actually the higher is the the zoom level, the less is the the horizon (I would say obviously), at least on my test.
And most times panning the map the horizon seem to disappear (you wrote me that's because the horizon script is working like that, but it's quite disturbing...).
So, to try to have to largest possible horizon, with every zoom level, I've (maybe naively) increased the count value to 9x9 (the default settings 3x3 didn't do the job at all).
But, this take obviously a long time to load, and unfortunately does'nt completely solve my problem.
With a "close-up" the horizon isn't visible... I mean, it's still there but it's not enough to have the perception of an horizon.
I'm using fog and camera clipping, but it's too unnatural to clip everything when, in reality,you should see much more far away.
Moreover I have some paths that should be drawn also at this zoom level, but them actually fly in the sky (them don't show in the attached picture).
You did a really great job, and I know that I should not even try to compare Google Maps with Online Maps so forgive me,
and I assume that I'm working with too large numbers, but I can't understand how to solve my issues:
Is it possible to fine-tune the Horizon script settings (and maybe the Map too?) so to:
1) extend the horizon (at least in "close-up" view), while keeping a good horizon quality (Google Maps as a reference, sorry)
I've tried to increase the "Zoom offset up to 5 but does not solve the problem, rather it's worse).
P.S. the best would be to have more or less the same horizon area (in Km) regardless of the zoom level, on the base of the memory
2) less perception of "appearing"/"disappearing" horizon tiles when panning the map.
I mean, when I pan the map suddenly the "piece" of horizon disappear, next I have to pan the map quite a bit before a new "piece" appear...
