OS2 weight class is set to 200 (Lightest weight)

When exporting my variable font with fontmake I get the Roman Extralight (weightclass 200) as default in the weight axis. Is there a custom parameter to change this ? And set to Regular (400) for example ?

There is Variable Font Origin. I don’t know if fontmaker is supporting it.

I tried that, it didn’t work…

Then you need to ask the fontMake people.
