Batch extension failing to generate OTFs from UFOs



  • I've generated UFO instances from Superpolator and I'm trying to generate OTFs with the Batch extension.

    I've been getting an error off and on. In the past, I've been able to change to a different number of source UFOs, then get generate OTFs. Now, however, I'm getting stuck, and it won't even work on a single instance.

    Here's the error message from the Output Window:

    Browsing around Google, it seems like this might be a problem that some code runs into with Python 3.6 when handling a dictionary without making it a list. Therefore, I think it might have to do with the interaction of ufo2fdk and my feature code?

    If you know of anything that might help, please let me know!

    this has already been solved in the beta...

    release is coming...



  • Awesome! (Is there any way I might be able to test the beta early, to generate fresh instances before I print materials for my graduation project?)

    RoboFont 3.1 is out – from now on all betas will be public!
