The official thread comes with a large amount of videos showing the new features.
A lot of improvements, but those hoping for Modo burnishing its full DCC app. credentials will be disappointed. The improvements are overwhelmingly focused on the modeling workflow (which includes a few procedural things), a couple of things for I/O with Unity and Unreal, a few new UV tools, the inclusion of AMD Prorender as the only notable render-related thing, a few things related to animation and motion graphics, and not much in other areas such as painting/sculpting.
In a way, it makes it appear as if Modo development is largely returning to its roots, which is Modo as a modeling software. In this case, I’m not sure if it will be enough to vault the app. to the sales target hoped for by their new owner.
That said, will the number 13 end up being lucky for them?
