%%%--- Operating System, Graphics card ---
Windows 7 64bit
NVidia GeForce 9800GT

- Blender version with error, and version that worked ---

Blender 2.67b has the bug
Blender 2.62 works in a much more predictable manner

- Short description of error ---

When performing G/S/R translations in Connected Proportional Editing Mode, the results become un-smooth if the mesh affected by the translation shares a common vertex. e.g. a cap on a cylinder which uses a central vertex instead of ngons.

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Open .blend
Enter Edit Mode
Ensure that Proportional Editing is enabled
Ensure that "Connected" is the active mode of falloff and that the AoE is large enough to affect all verts
Move pre-selected verts
Notice lack of continuity in the central circle

%%%Campbell:

Joe's commit 36181 added editmesh_set_connectivity_distance()

It's a strange function trying to include connectivity for weights. I can't find a decent use for it even. Just add a simple Mesh grid, and move a point.
Result doesn't seem to me having any use really...

Originally, the 'connected' option was only meant to restrict proportional edit to what's connected. %%%

%%%This was originally added by Martin:
http://lists.blender.org/pipermail/bf-blender-cvs/2010-February/025738.html

I think there are some valid use cases for it, one explained here:
http://lists.blender.org/pipermail/bf-committers/2013-April/039799.html

Perhaps this connected should be split into two options as suggested there. Maybe there's a good way to smooth such connected falloff, but I can't think of a nice algorithm at the moment.%%%

%%%fixed 2 bugs in editmesh_set_connectivity_distance() which wasnt working well

had feedback loop when accumulating distances so the vertex order would change results. r57527
the visit-hash wasn't working, causing this bug. r57532.

closing.%%%
