Armature layer dots not updated on changes
Closed, ResolvedPublic


System Information
Gtx 980

Blender Version
Broken: 2.8 current build

Short description of error
Usually if an armature layer contained bones, a dot icon is used to show that it's not empty.
However when merging two armatures, if one armature contains bones in a hidden layer, the dot icon is not displayed after merging.

Exact steps for others to reproduce the error

  • Open the blend file

  • There are two armature in the scene. "Armature1" contain one bone in the first layer (visible)."Armature2" contains one bone in a hidden layer (8)
  • Select "Armature2" then "Armature1". Ctrl-J to join.
  • The dot icon is missing on the 8th layer.

Event Timeline

lucas veber (lucky3) renamed this task from Armature layers: dot not displayed on armature layers to Armature layers: dot not displayed.
Sebastian Parborg (zeddb) triaged this task as Confirmed, Medium priority.

I doesn't seem to matter which way I join or if the are visible or not.
If I join 1 to 2, only the dots from 2 is visible and if I join 2 to 1 only 1 dots are visible.

@Brecht Van Lommel (brecht) who to assign this to?

I don't know since when, but at least in c59370bf643f, the dots on armature layers don't display, period. Edit mode, pose mode, after joining separate armatures, nothing.

The only way I found was by appending a skeleton from a 2.79 blend. But even then, the dots that were there the moment it appended will stay there for ever, even if you delete every bone.

This seems to be fixed as of at least a1ae04d15a9f, maybe longer. All the dots are working perfectly for me. Yay!!!

Edit: Fixed in pose mode only! :C If moving bones to different layers in edit mode, it's still broken.

Does not seem fixed in the latest daily build.

Yes, today I tried on several computers and does not work, there is no indication.

Brecht Van Lommel (brecht) renamed this task from Armature layers: dot not displayed to Armature layer dots not updated on changes.

I test with recent builds, script generate new edit-bone (bn) for armature, at same time set bone layer , bn.layers[16] = True
bn.layers[0] = False

bone move to layers 16, but the dot of layer 16 not up-date. and there seems no way to force up-date from blender UI

I want to recommend this bug to be considered High prio, since I think it will confuse or even turn off a lot of people from 2.80, if god forbid it stays in for the final release. Just a thought tho.

The description of the issue can be much simpler:

Moving bones between layers in edit mode doesn't show the dot icon in the layers UI. Works fine in Pose mode.

I hope this can be addressed before the release, while making the Blender Fundamentals training videos this issue pops up constantly and it's a pity to have to explain it is a missing update bug.

This only fixes the case for joining armatures, there is a deeper problem here.

This works great now, thank you! The only remaining issue is that upon creation of the armature, the bone layer still does not display there being a bone in the first layer by default. Everything else works great!

As Dillon Gu said, When generate armature as single bone from blender UI , bone can not show dot (though it is located layers[0])
so to show bone dot, I must need to change bone layer from blender UI. (3d view topmenu > Armature >change bone layers once)

but if I use bpy to change bone layer,
ebn.layers[1] = True, ebn.layers[0] = False , it change bone layer, but bone dots not up-date correctly. (dot should be layer[1])

Is there way to up-date it from bpy? if I must need to use bpy.ops ?

"bpy.ops.armature.bone_layers()" could up-date, without change current each bone layer.

if set bone layer by, or when all bone layer is default, layer[0],
run "bpy.ops.armature.bone_layers()" for one bone of armature, seems up-date all bones dot correctly.

amt = bpy.context.active_object
bpy.ops.object.mode_set(mode = 'EDIT')
ebns =
ebn = ebns[0]
layer = ebn.layers
