Hi Guys,
Just thought I'd add something to this thread that I discovered today which may, or may not, help.
So, I've been doing a repaint on the 737NG and downloaded the paintkit from the Aerosoft website. I did my repaint and everything went great and it looks lovely......until I view it at night! :huh: The lighting is all wrong on the tail and the engines.....doh!
I tried everything: repainting it, deleting and overwriting the night files, turning off layers. Anyways, finally I copied my repaint over the top of the original PMDG tail file and bingo! It worked.
So I started investigating the file itself and discovered the alpha channel in the "channels" tab in photoshop. After a short while I realised it was the wrong way up. So I flipped the alpha channel itself (not the rest of the image). Then I flattened and resaved the image and tried it out and bingo! Problem solved.
I haven't checked the rest of the paintkit files but I may just do that.
Hope that helps.
Regards
Andy
