How to edit different weights when using a multiple masters?

Hello Glyphs team,

I am currently working on a font using multiple masters. I have set the regular and bold weight as masters, but now I’m having issues with the thin weight. it doesn’t look right at all. is there a way I can edit each weight alone?

Thank you.

What masters do you have? It seems that you have a strong extrapolation.

You could add the instance as master with the Plus button in the lower left corner of Font Info > Instances:


… and then edit it. Or, if it is only a few glyphs that need extra attention, you can work with a Brace layer and reinterpolate just those glyphs.
