Slant axes result in messed up glyphs

Hey guys :slight_smile:
Iā€™m working on 4 Axis font - Sans to serif, Weight, Width and Slant. (Glyphs 2.6.7)
All first 3 axis works well but the slant axis mess my glyphs, what am I doing wrong?

Thanks in advance :slight_smile:

We need more information. E.g. your masters with their coordinates.

That helps?

Serif 100-900
Weight 100-900
Width 100-500
Italic 1-90


It took me a while: Glyphs 2 only supports 3 axes, you have 4.

Does Glyphs 3 support more?
