I don’t understand
I have a 3 axis font. One of the axis is set only for virtual masters:
Real masters have a value 0 in this third axis - all of them.
So some glyphs have special intermediate layers that have the value 100 on that axis. When I use the local interpolation custom parameter and want the font to export these glyphs at their EMSZ of 100, they don’t export at all.
These are the virtual masters:
You don’t need all those. It is only needed for the extreme positions to define the axis ranges.
So I need just one?
Most likely.
