Test out Tilt Brush-style rough sculpting in the beta now! (and keep giving us your extremely useful input and criticism please!).
This is the last update until v0.40, which will feature some major bugfixes (yes, unit selection and sculpting is kind of quirky in this version..) - as well as new parametric primitives.
The next version after that, v0.50, should be available late November / early December, and will feature texuring and painting, as well as new controllers and UX upgrades.
