In late 1990's existed a 3D modeling app Anim8or. (www.anim8or.com)

At the time, i used it to build morphs for Poser figures, selecting vertex by vertex by vertex.

That is where my love for the lower resolution figures came from. ( LOL.)  Morphing vertex by vertex by vertex, sometimes entering the X;Y,Z valeus manually to maintain symmetry, is very-very- time consuming, but Iearned a lot. Then came Hexagon, and it became my favorite, but the crashes, It works but is sooooo unpredictable unstable.
Some weeks it would work rock solid, and some weeks, it was unlivable.

Blender? I do not pretend to know Blender at all.
But I know a very small corner very well. The modeling, UV-mapping, the grouping, the material tools.
And NO crashes. The most reliable app on all of my PC's.

What I learned fom all 3 ?
For default human figures? => MAINTAIN symmetry at ALL cost at this stage.
Never mind me, I'v only been pulling vertex for some 20 years. LOL.

What I learned in all 3

Poser 1, 2, 3, 4, 5, 7, P8 and PPro2010, P9 and PP2012, P10 and PP2014 Game Dev
