Sorry for the late reply.
No, I am not one of the devs, simply a fan who occasionally comes across the site.
However, I do like the idea of replacing all of the npcs with matoran. So far, they have a build on hand. I'm not too sure it's completely finished.
They seem to have a combination of official and custom parts rendered to put together the models for rahi and the like. So I don't believe they need a program for that. I could be wrong.
