When I quickly made up a repaint when I was playing with the system I didn't edit the alpha files and didn't have the beige borders.
Yet I make a livery in the exact same manner and I get a beige border. Am I overlooking something?
If I am to edit those alpha files, what do I do with them? The omsi manual is not helpful in this respect - what do I put in the .cti file? What .rpc file do I use?
