Hello this might seem like a silly question but I've just downloaded the Airbus A320 paint kit for FSX and I was just wondering how do you change the image of the ModelConverterX with the Southwest plane on to the actual image showing the plane all white? Also I'm using Paint.NET not Photoshop
As far as I know Paint.Net supports layers.
Therefore you should be able to turn them off or delete them in the layers list.
However, you should read through all of them first. They're very helpful and prevent silly mistakes
Sorry, I never worked with Paint.Net, only Gimp and Photoshop.
Just checked the link by installing CS2 with it on my laptop and opened the PK with it perfectly.
I strongly urge you to use PS as the paint kit was meant to be used with it.
