Like Indigo Renderer, Kerkythea is working on a commercial product. Unlike Indigo a free version will stil be available, although it will not be as actively developed anymore.
From the announcement on their forum:
It was a long year of hard work and advances. Some people have spotted a delay in Kerkythea updates and indeed there was a reason. Our primary focus has been shifted towards the creation of a new renderer, entering the commercial arena. The name of the new renderer is - for simplicity - the same as the commercial engine that runs behind Kerkythea.Â
So, what is it with Thea Render? We believe that it belongs to a different class regarding quality, versatility and easy of use. This is a new renderer incorporating state of the art features with a lot of work and research behind it. For further discussion on the new renderer, we welcome users in our related announcement over Thea Render forum (requires registration to post or read).Â
And what about Kerkythea itself? We certainly won't abandon Kerkythea, our "render buddy". Most probably though, the shift in priorities will have an impact for the next updates, delaying them further. On the other hand, some related Kerkythea issues will be improved, particularly the integration with modelers (since exporters can be reused). And of course, there will be some long-promised features, that now make their appearance in Thea Render, but will also become available in a next Kerkythea edition.Â
Furthermore, we would like to reward the people that contributed to Kerkythea with the one or the other way (commitment, donations, hard work) as a minimal token of our appreciation and ask for their understanding for the shift of priorities.
