I have created a footprint in footprint editor and save footprint using add footprint libraries wizard, select the .pretty folder, the status stated OK and format is KiCad. And I put it to global library configuration so that next time when I doing another project I could call out the component.
In the footprint libraries manager I have the LTC3784
How did you try to access the footprint in eeschema?
Did you use cvpcb (The table like thing to set the footprints for all components)
or did you try to set the footprint field directly (library browser.)
If you used cvpcb have a look at the filter settings.
Place component (in kicad stable) does place symbols not footprints.
For more details about the difference between footprints and symbols please have a look at this post of mine: (click the post title to get to that topic or the arrow at the right to read only the linked reply.)
