Alternate layers with virtual masters

Glyphs
1

I have a virtual master that goes from 0 to 100 to make some glyphs wider. Some of these glyphs the narrow and the wider form are incompatible, so I need to use an alternate layer, but how to combine it with the intermediate layers used for the virtual master?

I tried this setup:

But Glyphs will not export the font and will give an incompatibility error:

I can get it to work by moving the two layers into a separate glyphs and writing feature variations substitution, but if there is a way to get this with alternate layers that would be better.

Can you send me the test file?

Only the second bracket layer should have the brace {100}. The first is just an alternate but not an intermediate.

Thanks, this works. Now I need to figure out why glyphsLib can’t handle it!

Please use the glyphs3-merge branch to develop new features.
