Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
As discussed in today's #animation_rigging module meeting:
Many selection shortcuts don't work in weightpaint mode.
f.e. to select a single part of a mesh you always have to go back to edit mode, select it with "L" and set the weights there via vertex panel.
It would be awesome to have following short cuts to work as well
Edit from @ChrisLend
In order to see the selection options you need to have either Face- or Vertex selection active:
This also makes the
Selectmenu to the right show up. This menu has different entries depending on which mode you are in.Operators need to be implemented for both modes and added to their respective menu.

Hello everybody, nice to get to know you all
If I don't go wrong with it , these ones are the files : paint_intern.h, paint_utils.c, paint_ops.c
we can add something like "PAINT_OT_vert_select_linked" in order to implement the first requirement (L to select parts of a model)
If we want to select the linked vertices, I would take MESH_OT_select_linked_pick in editmesh_select.c as a reference

So I started looking at this.
It's been a while since I used weight painting in Blender. But I found out that
{key L} and {key Ctrl} {key L} already work but only in Face select mode. Not in vertex select mode though
I will update the task with a more detailled description.

04aab7d516If the proposed keymap changes go into Blender 4.0 like currently outlined, the
Alt LMBkeybindings are already taken by other select operators:https://devtalk.blender.org/t/draw-paint-sculpting-keymap-proposal-feedback-request/29253
The idea is to make it more consistent across painting and scuilpting modes which keys are used for selection between left & right click select.
The main benefit for Weight Paint Mode for example is that
Shift LMBandCtrl LMBcan be used for inverted and smoothing brush strokes.Alt RMB,Shift Alt RMBandShift Alt Ctrl RMBwould be availible for loop selection in RCS. But this isn't as straight forward in LCS.is there a place for loop select then?
unless we make it a tool it's hard to put in a menu
The default answer to this question should be: Switch to a selection tool with the shortcut
W(Box, lasso, circle select)Then LMB is less in conflict beween action and selection operators.
So it would be a selection tool like the box, lasso etc tool
under here. I can live with that
Just to be clear, the loop/ring select operators would not be new tools.
They would be part of the keymap for the selection tools.
So instead of adding the shortcuts to weight paint mode, they should be part of the selection tools keymap.
Just noting that #83804 came up recently again, and taking away available keys somewhat contradicts having a key available to signal you actually dont want to select faces (but bones instead) -- this needs a bit of thinking though, just wanted to drop the case here.
just seen this now and the Loop Select is actually pretty important.
I switch to edit mode all the time to select loops. So I can set clean weights
when is "Set Selection Alt LMB" actually used ^^' It does nothing curently or it doesnt work ?
Couldnt google anything up
This was added in
98d48c16a3If it doesnt work for you, you could open a bugreport for this?
Btw., this task now seems complete?
Not quite the vertex loop select is still missing
stepping down from this because I don't know how to get the vertex loop select working
here is the abandoned patch
#108770: WIP: Paint: Vertex loop select
Also note that like I pointed out before, the selection shortcuts were updated and loop selection is only availible while a selection tool is active:
fb54d3f865Unless right click select is used. In that case they are available anytime.
as discussed in yesterdays module meeting this task will be closed. Loop select for vertices was running into technical difficulties and abandoned, everything else is done.
We can revisit loop select for vertices separately at a later date if required
