Hello Everyone, I will try and explain this as precisely and quickly as possible. I am flying the Overland 737-700 for FS9. I am using a Southwest Airlines add-on livery. I downloaded a set of reworked virtual cockpit textures. Using the DXTBmp program, I loaded the files into Photoshop to do some further editing. I was able to edit the replacement textures with no problem, I could save them as a .bmp directly from Photoshop and they would load no problem. Once those were to my liking I downloaded a set of replacement night textures for the VC. There was only one that I wanted to edit, to coincide with changes I'd made to the VC texture. I used the same process, loaded it into Photoshop and then saved it to the texture folder replacing the original 737ngvc4_l file (as a 24 bit bitmap this time). I start FS and reset the time so that I can test the replacement night textures. Every other replacement VC night texture shows up except for the one I made changes to. I don't really find this to be odd as I probably overlooked a certain step during save night textures except that when I flipped on the landing lights, my edited texture shows. I'm really at a loss as to how this could be happening. I tried different methods of saving or converting the file but nothing seems to make a difference, other than the texture not showing at all in some cases. If anybody has any insight I'd greatly appreciate it. Thanks, Rob

You cannot use a 24 bit BMP - FS won't read aircraft textures in that format. You will need to use exactly the same procedure you used with the day texture - load into DXTBmp, Image/Send to Editor, edit the image, then Image/Reload after Edit, and save it. Hope this helps,

No luck, followed the exact same procedure I did with the day textures. I still can't figure out why my modded overhead panel texture only shows when the landing lights are switched on, my mods become very apparent at this point. Even the part of the texture that I didn't mod still doesn't show until the landing lights are on. If I load the replacement VC texture without any mod then it shows up just fine, with all the other modded lights. Very weird, very puzzling.

Rob, I have a feeling that the *_L.bmp had an alpha channel, most do. Take a look at the downloaded night textures you d'loaded in DXTBmp & see if there is one. If so, save the Alpha portion, modify it to you tastes, then in DXTBmp combine your new non-alpha w/ the alpha in DXTBmp then save as extended bitmap. Not a painter, very little experience in it all, but have dabbled. Modifying an "alpha-ed" bitmap in PS or any other good paint program will ruin the alpha, you have to deal with both parts separately via DXTBmp, then recombine via DXTBmp. Roman

Appreciate your help, got it figured out. As it turns out I just wasn't saving it right when I converted it back to the extended bitmap using DXTBmp. I thought I had been doing it the same way all along, but I suppose I was mistaken. Thanks Again.

FS9 _L.bmp Alpha channels act as a binary switch: pure white for control by landing lights, pure black for control by "any other light switch."
