We do create C4D tutorials, but it's been hard to have the manpower to create tutorials for either version lately, sorry. For example, this time we focused on the Webinar rather than tutorials. We have tutorials planned for the new Corona 7 features, now that the webinar is done, with both Max and C4D tutorials being developed at the same time. Then if time allows, there is some catching up to do on Corona 6 features for both :)
