Problem trying to modify FSX sky textures.

[BraselC5048]

A couple of years ago, I modified just the nighttime HDE sky textures (the FSX version, just to be clear), to change the cloud/water/haze color. And they worked perfectly fine until a few weeks ago, and now they give bizarre lighting sky effects. (As well as apparently displaying the wrong texture for a given time of day.) I had figured it was a problem with the scenery I was developing at the time, but as now I'm transferring my installation to a new computer, I had the opportunity to try on a clean, fresh install of FSX (with Acceleration), and isolate the problem. The unmodified sky textures work, everything is stock and clean except for my sky textures, and my sky textures themselves are the problem. (At least they must be, right?) Since I've never actually seen it anywhere, should I include the 16 bit dither option in DXTBMP? The bmp's are extended 32 bit 8-888, the .tga's with alphas I converted from are RGB color, 32 bit, and going solely from file sizes, apparently (I can't confirm) the stock sky textures don't use mipmaps, while the HDE ones do. My version that has worked for three years until a month ago didn't include mipmaps. Trying my textures both with and without them, both had the same problem. Copying the entire FSX folder in from a backup from when they were working also somehow didn't fix the problem. FSX is set to the computer's screen resolution and 32 bit. What am I doing wrong? And why don't they work any more on a clean install, or a backup of from when they did work?

For the sake of anybody else who may have this problem in the future, I actually figured out the problem. Sky textures in FSX have one odd pixel, I 'think' the second or so from the bottom along the left side, as transparent. Well, somehow, for some unknown reason, that odd pixel out on the pre-sunrise and post_sunset textures I modified got changed to a brighter color. How, gods knows why. Changing the color of the pixel (before any alpha transparency is used) to the color of the pixel next to it fixed the problem.

 

Also turns out it wasn't running the wrong sky textures. I had assumed the entire 'midnight' series of textures I used had no blue areas of sky in them; I was wrong, they all did. I also discovered that, esphttps://www.flightsim.com/vbfs/editpost.php?p=2024082&do=editpostecially during the summer, the midnight texture set only gets used for a short period of time, and pre-sunrise textures start as early as 2-3 AM (or something like that.)
