I’ve noticed that compatibility checking does not always check masters after the sixteenth master. For example, I have a font with eighteen master. I‘ve masters 1–16 and 18 are compatible, 15 and 17 is not. But once I correct 15 the red bar indicating incompatibility disappears, despite 17 being incompatible. So far I have only seen this problem with node counts.
Off topic: WTF!! 18 masters??? picture! picture! picture!
It’s just the new version of Ironstrike with three width masters. The “italic” is an oblique with a 17.5° slope. Martina Flor’s interpolated slope angle work in Wonderhand inspired me to do something similar. Once I get the project file set up it will be four widths and 7 weights of
5° slope oblique
17.5° slope oblique
I might die before this gets released because the thought of doing QA is horrifying.
Could you send me the file?
Could it be that the last master is not actually used to interpolate?
I just sent the file.
Thanks for the file. I could fix it. It had nothing to do with the number of masters but with your particular setup.
