I want to create a variable font with a mottled effect. To achieve this, I placed some reverse paths on one master and hid them on the other master, as shown in the images below. The left image displays the hidden reverse paths, while the right image displays the reverse paths.
I’ve checked the compatibility and tried to simulate the effect in Glyphs using interpolatedFontProxy. This is what I want to achieve:
However, in Adobe Illustrator and Wakamaifondue, the reverse path has a visible outline.
Is it possible to hide the outline, or is this a rendering engine problem that cannot be avoided?
Any replies will be greatly appreciated. Thank you.
