Once more the question: How can I recognize from the folderor file structure inside an aircraft folder that this is a GMAX created aircraft in an FS9 format?I don't currently know which aircraft I should try thisraindrop hack with. Of course none of the default aircraft that ship with FSX, I suppose ;)Christian

>>Once more the question: How can I recognize from the folder>or file structure inside an aircraft folder that this is a >GMAX created aircraft in an FS9 format?That's the simplest question to answer!The model folder of ALL] "true FSX SDK" models will contain TWO .mdl files: one for the _exterior and another for the _interior.If the model folder has only a single .mdl file, then is is definitely NOT an authentic FSX SDK model... :)

My Real Air SF260 has two .mdl files but the vc rain mod doesn't work with it while all my FSD aircraft have only one .mdl yet I have VC rain with those.The easiest way to check is to backup all your FSX VCRAIN****.BMP files then copy the FS9 versions to the main Texture folder and check each airplane with rainy weather conditions. I have found no adverse effects with the default and other payware aircraft using the FS9 or rlvcrain.zip files .

Why is it so diffcult to develop this effect for fsx? It's a GMAX related problem?And this video:http://m.youtube.com/index?desktop_uri=%2F&gl=IT#/watch?v=ivwzweKgWF4Is it only a special effect? Or is it FS9?737 from iFly doesn't have vc rain effect, owners said this.So for FSX we won't see any rain drops on future add-on? Pmdg 737 too?

Best reason as explained here.

There are certain things (controlled by shaders) that can NOT be modified in FSX when using DX9. Rain and Snow being one of them. In DX10 you CAN control the rain effect shader effect, because it is external (inside ShadersHLSL), unfortunately is not the case for DX9 and rain/snow, so you are out of luck here.

The PMDG 737 will not have VC rain drops as confirmed by them.There are some a/c that do have them built into the a/c model like the Lotus L-39, ORBX Lancair, a few RealAir products from what I understand.Basically, to get VC rain effects in FSX, it has to be built into the model of the aircraft due to the way FSX works versus the way FS9 did it.I cant believe thie thread is almost 4 years old, time passes so quick.

That's a shame. Such a great effect is left out by so many developers. The L-39 is a prime example of how it can be done. It's one of my favorite effects. I can't believe it was left out in IFly's 737. It almost made me ask for a refund. But, I really like the plane, so I'm sticking with it.I hope that they are added in a future update.

That's a rather broad indictment of "so many developers" because it is based on erroneous and/or incomplete assumptions.For FS9, MS/ACES had a very simple and reliable mechanisim in the sim just for this purpose: chained animations. These were specially named files that -when detected by the sim- would display a sequence of 16 bitmaps for a/c stopped, and an alternate sequence of 16 bitmaps for a/c moving. The speed of the sequence for moving bitmaps was continuously variable based on airspeed. "Getting it to work" was very, very simple and straight forward! :( For FSX, MS/ACES had to remove the chained animation engine for FSX native models, because it was incompatible with the new, shader based system. Support for FS9 native models was left in place, but they didn't supply the necessary bitmaps in FSX for them to work... Oops! :( That is why folks running FSX have to download the required files from MS directly*, or copy/paste the 32 bitmaps from their FS9 ..\Texture folder before "vc rain" is restored to proper operation! B) To duplicate the "vc rain" a la L-39 and a handful of others requires that the modeler write a complete, custom system of his own, and create the 32 required bitmaps as well, because it would be a copyright violation to include the "default FS9 bitmaps" in his/her download package. The alternative would be to specify using the (non)default FS9 bitmaps, and require the customer to download and install the official MS released bitmaps manually, or copy/paste them from an existing FS9 installation. This latter approach is unlikely to make the customer very happy! B) Worse still, every bit of "glass mesh" would have to be duplicated an additional 32 times, increasing the size, complexity and performance hit on the model. For a small aircraft with only a single canopy it isn't that much of a hit, but for an airliner with many, many windows it would be!And now, as the late Paul Harvey would have said, you know the "rest of the story..." :(*NOTE: http://www.microsoft.com/Products/Games/FSInsider/tips/Pages/SupportAlertAdd-onAircraftCockpitsOpaqueintheRain.aspx

Thanks to all guys, so we can hope that in MS Flight 2010 this effect will be restored in your opinion? New MSF2010 will use DX10 o 11?This effect give us more realism, and I think it's a must.
