First week of the Mastering Organic Modeling class!
Gio Nakpil has a great personality for teaching - chill but clear in message.
The first assignment was a "doing things the hard way" kind of project: Turning a zSphere into a cube, turning that cube back into a Sphere, and then pulling a Cube out of that Sphere. Catch was to only use ClayBuildup, hPolish, DamStandard, and Move (and Smooth of course) brushes. Masking was ok...I used a touch of LazyMouse (hopefully that was also ok ;) )
Squircle? Sphube? Sphox?
Basically reworking the surface over and over again until the desired effect is achieved. The only stopping point I could find was that I just had to - otherwise I'd still be working on it. Mildly lumpy but still good, yeah.
