Prevent extruded/poked vertices from inheriting vertex group they were extruded/poked from? Subject says it all.


Create icosphere
Assign all verts to vertex group.
Poke all faces.
I now want to select SOLELY the verts that were part of the pre-poked icosphere, and NOT select the newly poked verts.


It seems impossible. When I select my original vertex group, the poked verts are included even though I don't want them to be, and didn't manually assign them to the vertex group. Same problem happens with extrusion or applying subdivision surface.

Is there a secret "new verts don't inherit vertex group" setting I'm not aware of?
After 'poking' select one of the new vertices - ShiftG and choose Amount of Adjacent Faces then CtrlI to invert selection. Create new vertex group if necessary.

Should probably add that the behavior is the same as parenting - meaning the children inherit the vertex group of their parents...
