Although an early stage of work but I don't want to go back to the "old" rain display. It was very funny, although there was a lot of bad weather here in Germany recently, I could not find an airport with rain (nearby). So I used the "Thunderstorm" scenario (day and night). You are on the right way - another step forward for FlightGear. Thank you very much, looking forward for further improvements :-) Georg EDDW BTW: >> 5) If you have propositions... :) 2) it's raining cats and dogs in my plane !!! (fixed this issue) Not here - I got wet. Another one: sometimes the particles looked like rain, sometimes *a little* like snow (especially at night). This depends on the view (front or side view) and the flight-direction. I know, this is an early development stage but I just want to make this feed-back. Maybe you can make the particles a little smaller for rain? But these observations depend all on the "thunderstorm" scenario. I am still searching for an airport with "rain" METAR. And might be "snow", should this already make a difference in the display??? - This SF.net email is sponsored by: Microsoft Defy all challenges.

Yeah I get that too. The blank ground area is because when the new , better terrain textures were added , the equivalant winter textures weren't created ...

I am still thinking about making this a part of the base package or an extension to be downloaded separately. There is now a download link for the current development version of the EDGE 540 on my rbar page at http://www.t3r.de/fg/fgfs-rbar.html It is still under heavy construction, but you may already check it out and have some fun with it. But beware, it is nearly unlandable due to the lack of flaps or speedbrakes. The FDM needs some tweaking here and there...

Hi, I propose my first tries... still much work to get a good implementation. >From the README (into path) : - This first try permits to add a basic snow and rain effects in using particle from OSG.

I tried a quick Google to see if I could find any rules/formulae for visibility due to atmospheric conditions but didn't hit anything. It'll be interesting if you can come up with rules or a formulae from your analysis of a large set of METAR data. LeeE - This SF.net email is sponsored by: Microsoft Defy all challenges.

When there is something like FG (fog) it is most likely that the poor visibility is limited to only the lower few hundret feet or so. There might be something like blown sand in some areas of the world that creates a poor visibility in a METAR in a perfect dry atmosphere without any clouds and perfect VMC (except for landing).

I've wanted this for years. There's more, too. For instance, farmland looks different in different countries -- when we went to the more photorealistic textures a couple of years ago, we dumped a texture that I think Erik Hofman had created for farmland that, on one hand, looked less like a photo and more like art, but on the other hand, looked *much* more like farmland as you would see it in England and parts of northern Europe. And I remember Paul Surgeon creating one that looked *exactly* like farmland in places like Indiana/Illinois/Iowa, but not like in the western U.S. and definitely not outside the U.S. Middle Eastern/central Asian cities look different than western ones. And there ought to be different parts of cities -- the types of buildings you see in the inner city (and their frequency) should be different from the types you see in suburbs, and both sets should be different in different places around the world.

I guess some of these issues could be improved that way; but lines of constant latitude or longitude aren't really correct, even for the ones they would improve. The region boundaries won't look realistic. The right way to do it is to use GIS data in TerraGear, and to expand the groundcover types coming out of TerraGear. Once upon a time, it was actually in the works to start creating those groundcover types/material definitions, in advance of actually labelling ground polys with them in TerraGear, so that people could experiment with setting them in fgsd; but I was gone for a while and I don't know what the status of any of that is now. -c -- Chris Metzler [EMAIL PROTECTED] (remove "snip-me." to email) "As a child I understood how to give; I have forgotten this grace since I have become civilized." - Chief Luther Standing Bear signature.asc Description: PGP signature - This SF.net email is sponsored by: Microsoft Defy all challenges.

This is fantastic - thank you very much! I have been thinking for a while that it would be good to have some way to have a finer granularity within materials.xml. For example: - Towns and villages in different countries/continents are quite different in terms of the buildings, and it would be good to reflect this. - Tropical forests are quite different from that of temperate climates - I did a virtual flight over Denali recently, and due to the limitations of the current terrain definitions, large parts of it were "forest". I think that as well as a property defining the season, it would be good to have a set of properties based on the geographical region, for example: /sim/geography/continent (africa, europe...) /sim/geography/climate (tropical, temperate, arctic...) I'm sure we can think of some more. If we could define these regions based on lat/lon (in an XML file?), FG could set them, and they could be easily used within materials.xml. -Stuart ___ Yahoo!

Microsoft(R) Visual Studio > 2008. > http://clk.atdmt.com/MRT/go/vse012070mrt/direct/01/ Hi, after using my old pc, because my old one is crashed(can't boot)I noticed that the perfoamnce wit data paging is much better! Even with a visibility more than 30m I can't see much impact. Before data paging I never could use this range! I think we could change this - FGFS would looking a little bit more realistic and the perfomance issue is small now. With OSG Perfomance get better and better - why should we stay back from our possibilities?

If we have to make something up because there is no information, should we then take something that makes fgfs crawl and look ugly, or rather something faster and prettier? We chose the latter.

In reality it is sometimes much higher (witnessed 50-60NM myself on a cold springday), sometimes not. Think someone did a conservative choice here.
