Random artifacts when combining Roughenizer + RoundCorner filters

Hello Glyphs People! I’m constantly seeing some weird open path jaggy-ness when combining the Roughenizer with RoundCorner filters. Typically, I like to have Roughenizer first in the list, then RoundCorner to smooth out the angles. However, sometimes some spikes appear on certain glyphs. It appears random, with it disappearing or appearing even when simply hitting Save. Assumably due to the way Roughenizer renders at random?

Anyhow, nothing I do to the paths themselves seems to work, but running Roughenizer on its own without RoundCorner following it seems to make it go away.

Thanks! I’d rather not create a whole extra set of glyphs to get the effect :slight_smile:

These are edge cases that can appear when short segments at an acute angle get rounded.

Try wider segment lengths to give the rounding enough space. Or run the delete short segments filter between.

Or perhaps don’t round a roughened design at all. It’s an awful lot of extra data and rendering CPU for something that cannot really be seen (unless you zoom in so far that you can’t read a word anymore).

Ah, I see, thanks. That makes sense. Is the fact that it’s happening randomly due to the Roughenizer filter adding random path anchors each time the font is saved?

Yes.
