Hi, I am not sure exactly what I am missing, but when I export the static font files, my all of my kerning groups change to other groups that I did not define.
I am on Glyphs version 3.2.3, and my typeface is built on components only, which I remove overlap to export that static otfs. It is admittedly a strangely built typeface, but it seems like the kerning groups/ kerning should be getting exported, and not getting replaced.
Please let me know if is something you have heard of before, or any common pitfalls I am missing.
The names of the kerning classes are not stored in the font. When you open a .otf in Glyphs, it has to guess new names and picks the name of the first glyph in the class. So that can be different from your original names. And debugging kerning by opening it in Glyphs is not a good idea, as decompiling binary font data is not trivial (kerning should come through fine).
