On one of my repaints I have created custom cabin textures. The day files work perfectly but for some reason the night textures will not show and restore to the default pmdg texture. I have both (pmdg_737NGX_cabin) and (pmdg_737NGX_cabin_night) in the texture folder and the alpha layers have been edited. Thanks

There is an active painters forum here at AVSIM and most of them are familiar with PMDG.  You might get a quicker response there.
