Manipulating the 3dmodels itself and making that manipulation available to the public afterwards would be clearly a break of the EULA as the copyright is owned by Aerosoft.
Only the paintkits are declared as public domain so far. The acronym MCX i interpret with ModelConverterX and this is a software that is not published nor supported by AS
for manipulating our delivered copyrighted objects. So we cannot guarantee ever what those software does to the models. The tools we use in production not contain MCX.
Is that personal livery a fantasy one or does it fly for a real world airline?
