“””””” However, I didn’t quite understand the third one””””””

The first 2 showed “if you were the creator” and keeping your curves to use with history (5 point curve for 500 point surface) you can get creative to “kindof” get what you want by moving a mass of points smoothy with just 1 pick point.

The 3rd one was me thinking “how do i apply it if YOU send me a surface with 500 points and NO CURVES.

So the 3rd vid is showing using flow and using a DUPLICATE of the mass point surface. In theory to get the “less points” to use.

But as an afterthought, i would still need to build a surface to gain access. I would probably attempt this with iso curves on the surface then rebuilding the curves to get simple curves to use. (If i could do that, that would eliminate FLOW!!)

So you got something out of it! We (and others) can explore more this for “scenarios” to see if its actually viable or false. Certainly not a replacement for poly soft selection but maybe a good lick in the toolbag?

Let me know…
