Changes to .otf file are not saved when exporting

Hello, I am having issues when exporting an .otf file. Any changes that I make to the font are not being saved. [I have attached wetransfer link that demoes the issue]

I am applying colour fill to an individual element and then I proceed to export options. When I press export, the file replaces the old one and I am sure that it does, because when clicking Get Info, the date that this file got modified is updated. But when I open the new replaced file none of the modifications I have made appear. Am I missing something?

I have scrolled through numerous forum posts, and I have checked similar issues, like the cache ones, but I do not think that this is the case here. I am in trial mode.

Where are you opening/checking the exported font?

Do you use FontGoggles for example? If not, you should :wink:

I didn’t watch the video before my first answer. Now I did. I think you are confusing OTFs with workfiles.

You need to save the file as a .glyphs file in order to store data like color or basicaly anything. You cannot open and modify a OTF file directly.


Please also see this tutorial:

I was about to mention that, too. I have saved the project as a .glyphs file. Still, If I export that file into an .otf file, I do not get any updates whatsoever, aka the notation program I’m using the glyphs for, does not render the colours.

Also this program is compatible with “reading” colour tags, If I can say so. Sorry If I am being stupid, I am a newbie haha

Did you also read the tutorial about color fonts? I would recomend that, too. Then you’ll have a better understanding of what happens (or not happens, yet).

Before the export of the color font, you need to add an additional parameters that store the color data. There are different tutorials (SVG using Color layers, CPAL/COLR using Color Palette layers) for that depending on the strategy you chose.

In the case you use Color layers (SVG strategy):
Open the Font Info → Exports → select your instance on the left side → Custom Parameters → add the parameter called Color Layers to SVG. After that your exported otf file will support color in Adobe applications and in some (but not all) web browsers.
