No, it is not my preferences at all. :) Actually all this glass plays are not rocket science at all. If you 'd like to change tint or add\remove dirt:
1. Find appropriate texture in unit folder. You can use any DDS viewer to view DDS files.
2. Edit Alpha channel in texture to change transparency. Main rule - BLACK = transparent, WHITE = solid, anything in between is shades of transparency.
3. Save DDS as DX5 (NVIDIA plugin required for Photoshop, have no idea on the other editors)
4. Replace original file or add modded file to additional folder (as it is in my mod for Mig-15)
You also can change texture itself if you like to add come colors on glass.
P.S. At the moment I'm unable to check if mod already approved or not, so keep your eyes on main side, Users Files Section.
