Hello guys.
So I read that you have to place every time your package in the community folder to be able to see your models. You don’t have to. Just leave the buildt package in the Package folder. Your models will be then shared, I don’t know why, among your project that have a package buildt in the Package folder (try and you’ll see). To be able to see the model tho, once choosen the project, don’t immediately build the package but instead load it. Now the model will be there. If you build the package first, you won’t be able to see it. If you remove the package from the Package folder, the step to do are the following: open Msfs and ONLY build the project, re-start Msfs and ONLY load the project. All your stuff will be there.
