I’m a little puzzled as to what’s really new about this? C4D has had ‘live’ boolean generator objects for years, they are animatable too. I guess the difference is that this produces relatively clean topology? (the C4D ones rarely do unless the geometry is very simple).
The video would have had a lot more 'wow' factor for me if they actually showed a wire of the mesh it was producing.
No disrespect to the Modo devs, I’m sure it’s a great app, but I get the same feeling watching this as when they demoed their rigging system a couple of versions back, claiming it was groundbreaking. It looked a lot like the FullbodyIK/Human IK systems in Maya/Motion Builder to me.
