Whenever there's a cloud in contact with a mountain top, the clouds flash. It really bugs the crap out of me and was wondering if there's a fix for this. Thanks.

Hi,Not completely. You can raise the clouds levels if you are using your own weather or use X Graphics clouds as they flash less.

Thanks Skorna. Any other ideas?

Flashing clouds on mountain tops,Burning like a silver flame,The summit of beauty and love,And Venus was her name,She's got itYeah, baby, she's got itI'm your Venus, I'm your fireAt your desireWell, I'm your Venus, I'm your fireAt your desire Ooops, sorry, I thought it was karaoke when I saw the thread title. Seriously though, it's probably the limitations of FS, one of the things they are working on in Flight apparently. Al

Is HIGHMEMFIX=1 in the [GRAPHICS] section of your fsx.cfg?

Chock, hah! Good one! :-) Paul, yes, I do have HIGHMEMFIX=1, why do you ask?

[GRAPHICS]HIGHMEMFIX=1 // Fixes LARGEADDRESSAWARE issue with D3DX Libraries for shader compilation - Bojote - Tips & Tricks, plus texture flashing from his other Avsim posts. .. also setting Water - High2.x will stop texture flashing, but both fixes may be contingent upon Shaders v3.0 being used.

This fix has been around for several years and works: "Go to this folder: FSX\ShadersHLSL\misc There you will find a file called SwarmCloud.fx. Make a backup copy of this file somewhere. (as always no crying if you don't do this step) Open the original SwarmCloud.fx in notepad or wordpad and then look down about 20 lines down from the top. You will see this entry: bool NewMaterialUsage = true; Change its value from true to false. Make sure to keep the semi-colon. Save and close the file. Now, go to C:\documents & settings\<your username>\Local Settings\Application Data\Microsoft\FSX\ (If you can't get to this folder make sure that "show hidden & system files/folders" is turned on in your windows folder options.) (This is the XP path by the way, Vista users will have to hunt for their equivlalent in the users folder.) You will see a folder there called: Shaders. Either move that folder out of there or delete it. Don't worry, FSX will build a new one the next time you run it. It contains a cache of the compiled shaders. This folder must be removed to ensure that the change you made to the cloud shader file above will be compiled and used on FSX's next run. That's it. Run FSX and enjoy very solid and reliable clouds! I haven't seen any other bugs or oddities crop up from this change. I've had a few friends who were also experiencing flashing clouds test it as well, one on nvidia, the other on ATI, and their clouds stay perfectly put now." Kind regards,

Spirit, thank you so much! I will try this when I home today and let you know how it works. If it works, I'm going to be a very happy camper!

Boy you sure have a good memory, Stephen!

Stephen, This is what I found: < string Name = "SwarmCloud"; string Class = "Basic"; bool NewMaterialUsage = false;> = true; Exactly as you see it above. It is already false. Perhaps the "true" below the NewMaterialUsage should be changed to false?Please bear in mind that I am using Bjote's shader 3.0 for clouds only.

Also, would either of you know what's causing this straight line in cirrus clouds? I see it all the time.

Hi, That's the divider between your post and your signature. A screen shot might help!!

Hi Jim, Woops I forgot to attach the screen! Here it is! :-)

Hi, That is some ugliness. What cloud textures are you using?
