Proportional editing does not influence all objects in edit mode

When enabling proportional editing with two meshes in edit mode, the proportional editing does not affect the other mesh, as if connected proportional editing is enabled instead. Proportional editing works on either of meshes when they're both in edit mode, but doesn't influence the other at all.

  1. Create two separate objects. (two intersecting spheres for example)
  2. Select both objects and enter edit mode
  3. enable proportional editing.
  4. Select and move vertexes on one or both objects that are within proportional editing range.

Philipp Oeser (lichtwerk) raised the priority of this task from Low to Normal.

Think this would be nice to support, will check on this...

@Philipp Oeser (lichtwerk) I just saw you start working on this.
I was trying to solve this for couple days.
I was still at an early stage, and had many problems.
All I had was a prototype, working for vertices for simple mesh.
I have checked only vert slide, to work together.
By my calculations there are maybe 100 cases need checking/work (>_<)

If you didn't start (or finish already) maybe can make use of it ...or maybe it is as bad, as I feel it is.
Either way I'm looking forward to see how it should be done
Especially if you use parts from this diff, to see how you solve some problems. (can only hope.)

@George Vogiatzis (Gvgeo): ah, didnt know you were on it...

Will check on this (might take a bit though)

That's okay.

I avoid claiming tasks without reason.
I try multiple bugs, and drop them if I can't finish them.
Usually I wait till they patched, and see how should have been done.

This is one of these cases, it looks too complex, for me to make a patch of it.
But because I had a basic (working?) idea, thought/hope it may help you.

note: there are D3993 and D5163 to check on as well...

At the moment, while proportional editing, selected vertices will only 'pull' unselected vertices from the same mesh. D3993 or D5163 allows selected vertices from one mesh to pull vertices from other meshes. On their own these patches don't fix this task.

From memory, another problem that needs addressing before this task is complete is that a mesh without vertices selected will not have its data included in the number crunching. For non-proportional editing that's okay, for proportional editing it causes the problems described in this task.

@Philipp Oeser (lichtwerk) This task has was assigned to you a few months ago, how's it going? If you're not making any progress would you allow me to take it off your hands? If you're ok with me taking it off your hands, I'll include it into D3993/D5163 to make a complete patch that covers this task.

Hi @Alan Troth (Al),
yes, I think this in good hands if you take over (I basically claimed this as this was TODO without knowing anyone was actively working on this... and I have hands full of bugs anyways...)
Thx for poking me, makes total sense, will assign to you then [looking forward to your work]

Any update on this? This is a much needed feature and still broken in 2.81a.
