It would be fantastic Armory would be able to support grease pencil rendering in games
I do not know how to implemented a custom shader in armory, but there is a sample code of the cartoon shader:
In this code, needed delete the halftone sections.

Armory actually did support grease pencil at one point. I saw a web-demo at one point with an animated grease pencil drawing. I’m assuming it was removed because of API changes in Blender 2.8, but I’m not for sure. I’m assuming that it will be coming back sometime now the Blender 2.8 Beta is out.
When you look at video on 16:30, this is what would look great in Armory.
Grease pencil animation in Armory would be the really fantastic feature!
