COMPRESSONATORGUI
If you make liveries for the sim, buildings, or effects, make or manipulate PNG files for the sim using GIMP and Paint.net, there is a better way to finalize your textures, you should check this out:
I just discovered a little program at GitHub that renders PNG files with BC7 compression when saving as a DDS file for livery artists as a final step before the sim folder. The program is called CompressonatorGUI and it finalizes the entire PBR set ALBD, COMP, NORM far better than Paint.net for NORMALS, and GIMP's outdated DDS plugin. The results it the sim are very noticable. I was unaware that GIMP was carving so much detail off my DDS conversions, all the while maintaining a huge uncompressed file. Using Compressonator now, I've gone from *64mb files to 16mb files and they look incredible in the sim. I don't fully comprehend the algorithm manipulation, or the code as described in the Youtube video, but my eyes do not deceive. I have gone back and redone all my current B-25 liveries, I thinks it's that good. It's just a little time consuming setting up mutiple PNGs for conversion as you need to tell the program how to handle the files and where to place them. But I swear the results in the sims (20 and 24) are amazing. It also converts PNG directly to KTX2

Because this program can run off of a .bat file, I used ChatGPT to help me write an automated conversion .bat for converting my PNG to DDS through Compressonator reducing my workflow time considerably.
If you intend on using the .bat file feature, you must download and install in the same location - CompressonatorCLI
GUI is the user interface which works great as a stand-alone, ChatGPT determined we needed to include the latter to aid the automated process.
BTW, the title of the program may be called "Compressionator" but the .exe file is called "Compressonator". Typo? Intentional? Don't know, but the difference doesn't seem to have any negative affect on the functions or features.
* 16mb was the result of 1 mip level. For a full set of 13 mip levels from a 4096 x4096 texture, the file size became a total of 21mb. Still, a significantly reduced strain on the processing with the reduced size, and extra LODs.
