Hey everyone .. I'm trying to make some cargo planes from PMDG 737's for P3D v4 but i just cant seem to remove the window seat ports, i just need someone to point me in the right direction.. thx

Do ya mean the Windows?

yes

 

Ya just need to remove them from the main livery which ya probably done already and the Alpha layer remove the windows which ar ein black and turn them white color

If unsure see open up my west atlantic livery on avsim to see the alpha layer

Hi gnt586, I'm new to painting I cannot figure out where the Alpha layer is to remove the windows.  Can you point me in the right direction?

Alpha channels can be easily extracted from and ( after being edited) re-imported in texturefiles using a great tool named DXTBmp.( made by Martin Wright ) 

See the Painting FAQ   Question/answer nr 2
 

Open the files for the fuselage in DXTBmp and you`ll  see the alpha-channel  in the little window at the right-top-corner of the program.
Choose the option Image> Send to editor and edit the file,save the file in your paintingprogram ( JUST save , not save as) 

Then choose the option  Image>Reload after edit and save your file to the desired filetype.
MIND when saving you can choose between saving with or without Mips ( Mip-mapping) , I usually UN-check Mips to have the utmost quality when looking at the plane in sim.
