Hidden meshes on fbx models

hi,so i found this fbx model of a car and most of the parts are missing and cant be touched
they are available in the object list but pressing ALT H doesnt show them and i dont know how to


Did you try the screen render icon ( the TV-looking icon ) in the outliner filters?

uh is there a way to show all of them instead of clicking one by one image

Left Click the first in the stack…hold shift and Left click on the Last…selecting all between ( this will stop switching on any that aren’t selected )

Now you can hover over the first disabled part Hold shift and Left-Click and Drag down the row of screen icons and it will change the visibility … it can also switch the visibility of any that are already on.
