Creating Serifs with Corner Components: Challenges in Exporting VF Files

Hello,

We are working on a serif typeface project using corner components in Glyphs 3.3 (3337). The typeface is designed to support two optical axes, and the goal is to generate a variable font (VF) file that meets all functional and aesthetic requirements.

Current Progress

  • The serif design relies heavily on corner components for consistency and precision.
  • During export, we successfully generated both OTF and VF files. However, while the OTF version works perfectly, we encountered issues with the letters x, y, z in the VF file. These issues are not present in the OTF file, suggesting the problem lies in the interpolation or export process specific to the VF format.

Challenges

  1. Interpolation Issues: It seems the affected glyphs may not be interpolating as expected in the variable font export.
  2. Component Handling: The corner components might not be properly resolved or flattened in the VF file.

Questions and Request for Advice

  • Are there best practices for ensuring corner components function consistently in both OTF and VF exports?
  • Should we consider flattening corner components before VF export, or is there a more efficient solution within Glyphs?
  • Are there tools or methods to debug specific glyph issues in the VF file (e.g., pinpointing where interpolation fails)?

We aim to refine the design and resolve these issues promptly to ensure a robust VF output. Your insights or recommendations would be greatly appreciated!

Thank you.



Can you check the alignment settings in all masters. And do you have “origin” “left” and “right” anchors in the right places in the corer?
