Glyphs 2 and more than 3 masters

Does Glyphs 2 still support only 3 masters?

I wanted to make use of a custom field to create optical sizes, but when I add 4th master, I cannot generate instances.

Glyphs supports more than three masters for years not. What’s new in Glyphs 2 is the third dimension. If you configure it correctly, it works. If you can’t get it to work, please send me the file.

Ok. thanks. I sent You a file.
