Hi,
A few weeks ago, we could update a UIFont prefab just by drag&drop the config (txt) file onto a field in the UIFont inspector, and it would update the entire font and fix it.
The field is not here anymore :/
I'm using TexturePacker to create my atlases, and it was the way I updated fonts, now the only way I can make them work, is to use the NGUI atlas maker.
Is there a reason you removed this config file field ?
Thanks.
