• Summary

Characterworks is a software suite for character generation. It uses an HTTP-based protocol, utilizing sending commands formatted as JSON. The protocol is reasonably well documented. In order to be useful in context of Sofie, the module should support playing Motions & setting text values for layers.

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)
