If you already tried to use OpenToonz, then you probably noticed that its bitmap drawing capabilities are pretty limited. This is why, despite of its feature-rich animation toolkit, OpenToonz cannot (yet) act as replacement of Krita in the area of frame-by-frame animation.
Several people pointed out, that it would be awesome to integrate MyPaint brushes to OpenToonz.
Our hired developer Ivan Mahonin already did a preliminary analysis of the task and considering to implement this feature. Unfortunately, I have not enough resources to compensate his efforts, so I have posted a bounty to make this happen.
I would appreciate if you help to spread a word about it. Maybe someone will want to join me and pitch the reward amount. Anyone is interested in this feature? ^__^
