I am working on a variable font with 3 axes, the first one is “weight” and the other two are custom.
I am using the bracket trick to switch shape to a letter, this should only change when using the third variation axes (I call it INSIDE).
Testing the font on Font Gauntlet and AxisPraxis works without problems, but in Illustrator (version 2022) it does not work. I have tried it in InDesign, however, and it works there.
Does anyone know why? If I use the bracket trick on the first axis (weight) it works, it is only when I use it on the other two that it seems not to work. (I have Glyphs version 3.1)
This is an Illustrator bug. You can set the custom parameter Feature for feature variations (or something like that) and set it to rlig. This makes it work in Illustrator (I think that was the feature, I might be wrong).
