and how do you render your nifty, sorry im a total newbie..
5

Obviously it can't find your font file.

Try first with default font? :slight_smile:

6

cant find the default font too… my atomic font is in the project's src folder…



Where do classPathResourcelocator and relativeResourceLocator look for the files?



Thank you
