Hi anyone knows why vertices outside the radius get influenced too during proportional editing? The .gif is in right ortho with smooth falloff. Note: Verts outside the radius are the bottom left vert connects to 5654, the vert on the right of 5887,the vert on the right of 5881, the vert on top of 5827, the vert on top of 5928.
The radius displayed is an indicator of influence from each of all selected.
A single vert selection only shifts other verts within the radius Suggest the radius of influence applies from each vert.
Simple test on grid eg select two verts outside circle, appears to confirm this.
Notice with two verts selected on grid, both outside the displayed radius of influence, move verts of within the radius of influence of each.
Each vert that moves is within the radius distance of a selected vert.
In your question image no vert is being moved that is not within the radius of another selected vert.
