Ok I dont know how to really explain this problem but ill try my best
When I open the textures in Spark IV, eg. bus, I edit the livery for it but in Spark it shows just the images but the background of it looks sort of like a grid? But when I edit in Paintshop and save and import, no matter what it makes the background solid white so it messes everything up.
How can I edit the images but keep the background looking like a grid?
