I’ve been trying to recreate something like the intro sequence to the Enter the Void film. See it below from approx 01:10 (warning: flashing images):
There isn’t a way to set a key frame for Font Family so I used an expression on the Text node. It was here that I noticed a few oddities.
I’m using Natron 2.3.15 on Ubuntu 19.10.
If I just enter frame in the expression editor and press play the Font Family drop down menu updates on each frame but the font display doesn’t change.
If I enter Text1.name.set(frame) and press play the Font Family and display updates each frame. However, when I try to render it just renders the first frame.
Additionally, no matter which expression I use, if I close Natron and try to reopen the project the program automatically closes. The terminal shows this output when it crashes:

Has anyone else experienced this issue? I’ve attached my project file.
