Looking for advice on how to repair this large and deep damage to an outside corner on an old wall. Materials are plaster over rock lath, for what it's worth. You can see the rock lath through the plaster in the first photo. Haven't found anything online about how to repair a corner with damage this deep.
In the second picture you can see the big picture of what I'm repairing. Just as a sanity check, I'm repairing the other smaller corner cracks with mesh tape. There are also some small hairline cracks that I'm skimming over. If any of that sounds wrong, please let me know.
