What does "Simplicify" do?

[24c]

Thanks Eric & Bobby,

I've only ever used 100%, as I reduce the mesh in 3D Coat or BalancerNPro afterwards.
My artefacts then are caused by the meshing function, that's interesting.
Would increasing the turntable steps, although making a bigger model help in filling in some holes in the mesh?
The problem is really the undercuts on the surfaces like the piston ring recesses.
Maybe it would it be best to angle the object to get the camera to see more of these straight on to reveal the detail, but what you gain in one area, you lose in others.
Ideally, I think, the turntable should have another axis, and then go through a controlled rotating and tilt sequence, and in doing so it would illuminate and capture more accurate detail in one pass of the object. The alignment in the software would be easier to program/interpolate etc.
Obviously this is a lot harder and more expensive to create... a new turntable or upgrade option Shining3D?
