I would like to use an existing aircraft (default or 3rd party), except, change a few things, let’s say insert new instrumentation through panel.cfg. Is that possible? Can I create a user aircraft type SimObject, but instead of including all of the assets (textures, 3D models), I’d like to alias them to the existing aircraft, except in panels, which I would not alias, but substitute with my own.
AFAIK, In 2020 not really, you can alias the art fine (models/textures), the sounds, the panel. But you can’t alias the .CFG files in the main folder (aircraft, flightmodel etc.). They would need to be copied, therefore you wouldn’t be able to share the work.
You could have a mod that overwrites the default panel with your own, but you wouldn’t be able to keep the original as selectable as well.
2024 is different and making just a panel variation would be simple.
THANK you for the answer! Yes, I was hoping to alias the GLTF files, just like the texture.cfg allows you to specify “fallback” texture location. Can MSFS2024 alias model (GLTF) folder?
It can, but instead, you would create another preset. A preset can overwrite any aspect of the original aircraft, so if you just want to change that panel or add new panels, you would do it with a preset. When you select that preset from the aircraft selection screen, it will have all the edits you made, while keeping the original also selectable.
