Yes as stekusteku says, it was much easier with MSFS2020. Definitely not as easy with MSFS2024, at least presently. Currently there is a difficulty converting ktx2 files to png using the tool(s) that are readily available, i.e. Nvidia texture tools exporter.
Have a look here….
It seems there is a bit of an impasse right now. I’m hoping someone will pop up with a solution soon.
