FS9 Textures in FSX - Graphical Anomolies

GreetingsI've been attempting to convert textures of various payware aircraft for FSX for the VA I'm involved with. I use 32 bit 888-8 encoding on all my textures for FS9. These textures do load in FSX, but various aircraft parts are lit incorrectly (doors are dark etc...). I still primarily use FS9 but may finally make the switch to FSX soon, plus many of our pilots have been requesting FSX textures as well. The first aircraft I'm trying to tackle is the QW 757. As I said 32 bit 888-8 BMPs load fine, but the doors are dark. So, I tried re-saving them as 32 bit 888-8 .DDS textures (flipping them of course), but the same problem occurs. I've attached a screenshot to show you whats going on. I've haven't tried it myself, but some of our pilots are reporting similar issues on the FSX LDS 767. I've only converted the fuse textures to DDS, so I'm not sure if the engines would match the fuse if I converted them as well (but there is no real change from when using BMPs). What format do I need to have my textures in?ThanksJoe Wagner
