Didn't try exporter yet and to be honest, not sure if i would want to. Even best exporter could only do half decent job comparing to manual publishing. But i have some questions about your product. I noticed from screens that it has ability to render previews. What render engine is used for that, what render settings and lighting is used, is there ability to evaluate rendered preview quality before publishing?
It seems that there's also options to export various additional formats, but again, is there ability to evaluate quality of convertion before publishing?
