4 axes – 3 Masters

I have a font with 4 axes and 3 Masters. In previous versions this didn’t seem to be a problem, now I’m in trouble when exporting a variable file (OTFs etc are fine). I’m getting the following error message:

Problem generating Feature Variations
In glyph: notdef: Master is outside of the interpolation space at 100 and axis rage: 0-0

Is there a way around this?

Can you show you masters setup?

Yes, here they are.

This setup has two axis, not four.

And the “Pre 5th” master seems to be the only one suitable to be the origin of the variation. Add a “Variable Font Origin” parameter to the font settings and pick that master.

And update to the latest cutting edge version.

And the Axis Location parameter is not needed if it has the same numbers as the Axis Coordinates.
