For the first one, it should be something like this: @patch celestial_bodies; :json celestial_bodies > data { @if $$bodyName == "Mun" { rotationPeriod: 800; isTidallyLocked: false; } } I tested only briefly, but it seems to work. For the second one, there's no direct replacement, since Patch Manager can only edit or create JSON files (which the games uses for the definitions of parts, planets, science, and things like that), but the skybox is just a texture
