Using MR2-115 (latest until next day or so, right?):Here's what I experienced that will either confuse or clarify an issue:METAR had a BKN layer at 700 AGL and OC at 2500. I do not have the option for ground locking weather enabled.Sitting parked at a nice "open" GA airport, after the refresh and update completed:1. Precip kicked in.2. BKN appeared nicely with O/C behind in upper layer3. BKN disappeared leaving just O/C or O/C had priority over the earlier created BKN.I was running the Reality-XP WX500 radar. Even after the BKN disappeared, the radar showed just about the same concentrated areas of precip.So my comment is:Is it necessary for the cloud layers to be fed in order to the FS weather engine top layer down to lower layers so visually the upper layers so not overwrite the modeling of the lower layers? It seems to take quite a while for each layer to appear so perhaps FS does not order the layers before rendering.What are your thoughts.

Hi,We feed in weather to FS via FSUIPC one station at a time, and FS can handle this very differently each time. Usually only distant wx is depicted (sequentially) during the actual writes, and then at the final "Process" (after all station data has been set), the "full picture" will activate. It really depends on the situation.What you are describing with the broken layer "blending" with the overcast is normal, especially if your system is lower on resources. Overcast always gets more priority in the FS9 wx engine. You can try turning off overcast enhancement and see if you like that effect better. Turning sliders down can also improve the rendering of clouds.Hope this helps!

So, if I interpret your response correctly, even though the OC ceiling is 2000 feet higher than the broken ceiling, on the next write the OC at higher level can delete the lower layer?As stated, I was still getting precip returns where the builds would have been. They appear to be there but just not visible.

Hi,Writes don't happen like that. ALL WX DATA is sent to FS then it is activated (this includes all levels, all cloud layers, etc). There is no ordering here.If the radar is showing the clouds but the sim isn't, then FS9 is not rendering the clouds (even though they do exist in the sim world). This sounds like possible Cloud Coverage Density not set to 100%, or as I mentioned, possible lower resources causing FS9 to skip/delete the render of certain clouds to keep your frame rate up.However, since we have a known issue with FSUIPC and WideFS at the moment, this could be the cause. Normally you aren't going to see layers of clouds build up one at a time like this. Could very well be related. Hope to have a new build out shortly!
