Variable incompatibility

Hi

I’ve managed to get a variable font working with 3 axis before but having applied the same set-up to a new font it keeps telling me on export that the “‘a’ is incompatible”. Have checked in the fix compatibility tab and all seems ok. Any common problems or issues I should look out for?

Thanks a lot!

Make sure your anchors match and that there are no stray points hiding in your outlines.

Have you read the Multiple Master tutorials? https://glyphsapp.com/tutorials/multiple-masters-part-2-keeping-your-outlines-compatible

Have made sure of this but still no blue lines connecting the instances :confused:

Yes have been through but and it should be working but I havn’t even got the blue node lines. Is there anywhere i can send a screen or file. Confused why this doesn’t work but others do.

You need at least on interpolating instance or add the “Force compatibility” custom parameter to the font.

I have ‘enforce compatibility check’ in use but can see the ‘force compatibility’. I also a have the font interpolating fine with 2 axis (width/height) but when i add the third (weight) they all break.
