I'm trying to understand why some plane's texture folders are different from others. I'm still fairly new at repainting. I successfully repainted one of Thomas Ruth's airbus models as all I had to do was find the "main" dds file etc. Since this was the first and only type of texture folder I did so far, I understand it well.
But some planes have bmp. only, some with dds only, and some with both bmp. + dds files in the texture folders where the parts of the plane is scattered into many files. Why do some use only bmp while some use only dds or both?
