I've just committed to origin/next a better fix for the LoD range that adjusts based on the view distance, and also attempts to account for the possible size of the cloud itself. Thanks - working fine here! Does this contain the impostor functionality already or not? Cheers, * Thorsten

It's actually surprisingly intricate. For instance, Local Weather allows for boundary layer gusty winds. For some problems (the wave pattern) you'd like to have the base (mean) wind at the surface, for others (windsock) rather the actual wind that the aircraft is feeling. I am now

The LoD is currently hardcoded to 20km, so if visibility 20km, it kicks in before the transparency effect. I have a good fix that takes into account the current visibility as part of the Impostors work, but that won't be available until after the release. In the meantime, I can

At view distances 100 km it becomes more and more apparent that the flightgear scenery is flat and not a sphere, doesn't it? I think a realistic horizon is impossible as long as scenery/world is a disc. What's more important from high altitude is what happens beyond view distance where no

We should agree on a common place to publish actual surface wind (for one or many given locations?) in the property tree. /environment/config is definitely not the best place to use but due to historical reasons, many objects rely on these properties (windsock, chimneys/smoke, many more).

Local Weather is now (almost) in the shape I would like to see in the release, and I've worked quite a bit through the list of issues: 1) Local Weather places clouds at the wrong altitude. I've corrected that. 2) The GUI is not consistent with the system (I will fix that) A new gui combines
