Hello, welcome on board.
First, you need to explain what you mean by different “skins”. Are you talking about converting 3D models/POI's?
In general, direct conversion is not possible, you always need the original 3D-models with the textures/images in a suitable format and the SDK-Plugins for export as *.tgi file (using Blender Plugin or MCX/Modell Converter X).
Hello, thank you. I have aircraft liveries, such as the Boeing 737-500, 737 MAX and 747. They are very specific liveries from Brazilian companies such as GOL, SIDERAL, VARIG and VASP, and I would like to recreate them on the Aerofly fs4. Is this possible? aerofly fs4 uses a different format in the painting files, such as TTX TMC TMD, is it possible to edit them? Which tool should I use?
