Import blurry edges from AI

its my first time using glyphs and I would like to import letters with blurry edges from AI into Glyphs. When I copy paste it, the letters always loose the blurry edges:/
Can someone help me with that?
Best regards

Fonts can only contain simple filled outlines.

There are some options but they need more work. You need to build SVG files and use them to build an SVG based color font: Creating an SVG color font | Glyphs

That might not work in all environment.
