This issue very much ties in with this other one: Live Weather - Toggle options (enable/disable) for METAR based weather injections
It is also directly related to the known bug: METAR keeps disrupting the weather/ bugged weather/Cumulus/CB clouds only/no medium to high cloud coverage
METAR Injection/blending seems to be critically involved in most cases where RW weather depiction falls short of the minimum feature expectations.
I.e: It is possible to set up extremely life-like layers of haze using static weather presets. However, with Live Wx, these areas ares of haze are invariably (and most unauthentically) confined strictly within those “Metar Crop Circles”.
This is yet another point that has suffered a massive downgrade since SU7, when Metar “blending” was added - Mind the quotes now, as there isn’t really much blending in fact. The edges of these circles are unnaturally hard and sharp.
All the more reason to have a toggle - Metar Blending is an extremely detrimental compromise that sacrifices a lot of quality in exchange for a little more* real-time accuracy. (*with dubious results at that)
It is not reasonable that all of us should have to surrender so much for these small benefits (if any) desired mostly by a minority subset of the player-base, that is: VATSIM users.
