Now there are some aliasing issues left in the letters. The only help or results I found about that, are “there is no way, you have to “hide” the flaws – working with even more blur, grain or whatever”.
Hmm, trying TIF instead of EXR now, maybe there is some change.
As for example. Actually it’s with every text in AFX. Just create a 2K or 4K comp, add some text, and export it.
