bad interpolation with intermediate layers #926

Open RosaWagner opened 12 months ago

RosaWagner commented 12 months ago

As mentioned in multiple issues that export fails because of brace layer names… well after normalising these names so the font can export, the result of the interpolation is quite bad.

On top export from Glyphs3, below export with fontmake:

Intermediate layer at 300, concerned glyphs are too thin until like 700
Intermediate layer at 400, concerned glyphs is too thick until later in the range
Alternate layer at 500 for a glyphs in a stylistic set, jump is not happening

you can find the fonts here: https://github.com/RosaWagner/mona-sans/tree/interpolation-issues

That seems to the the same issue than #851 and #925

RosaWagner commented 12 months ago

And I guess also #924

And I guess also https://github.com/googlefonts/glyphsLib/issues/924

I don't think so, that one seems to be about some other bug when going from ufo2glyphs, this and #851 occurs when going glyphs => ufo upon compiling

@RosaWagner can you retry using the latest glyphsLib 6.2.4 with #928?

thanks it's better :) Only he last issue listed is still problematic, but maybe it's a separate issue?
