In the “Creating a Variable Font” tutorial, https://glyphsapp.com/tutorials/creating-a-variable-font, it is specified that there is only the need to add the extra special layers to composite glyphs if the components have Bracket layers and not Brace layers.
The script “Composite Variabler” is only adding extra layers to the Bracket layers, but not the Brace ones.
When the fonts are generated though, all the composite glyphs that have components with Brace layers, the small adjustments made in the Brace layers are not following up in the composite one.
For example, in e, it’s the crossbar that is made heavier in the Brace layer, but in the accented glyphs of the e, this does not show. All the small compensations that happen in the Brace layers don’t follow through to the accented ones.
It is also happening with all the Arabic glyphs that have dots or accents above.

Thanks for shedding some light on this!
