System Information
Operating system: Linux-4.15.0-91-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: Mesa DRI Intel(R) Ivybridge Desktop Intel Open Source Technology Center 4.2 (Core Profile) Mesa 19.2.8

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-03-12 05:06, hash: 375c7dc4ca
Worked: (optional)

Short description of error
When using the AniMall addon to animate vertices, beziers etc. the "Only Selected" filter in the Dope Sheet and the Graph Editor doesn't hide keys for unselected vertices/beziers as expected but only for unselected objects, making animating more than a trivial number of vertices/beziers impossible.

Exact steps for others to reproduce the error
Turn on Animall in settings.
Select the cube and go into edit mode.
Select two vertices.
Press 'n', go to animate.
In the AniMall Dialouge, check 'Points'
In the AniMall Dialouge, click 'Insert'
Deselect one of vertices.
Open up the Dope Sheet and expand as necessary.
Both vertices are visible.

I have had a try at implementing this, and I don't think it can be done in AniMall as the required hooks don't exist in the main code. The best I think you can do is turn off the unwanted channels in the graph view (i.e it is not possible to hide them in the dope sheet using python). I have included the python code I use to do this below in case it is useful to anyone else, but it might not work in all cases. I had a look at what was required in the main blender code to properly hide unselected vertices, but it was beyond me :(


import bpy

def hide_unselected_vertex_fcurves(o):
    
    - get all selected vertices
    - we need to switch from Edit mode to Object mode so the selection gets updated
    mode = bpy.context.active_object.mode
    bpy.ops.object.mode_set(mode='OBJECT')

    selectedVerts = [v.index for v in bpy.context.active_object.data.vertices if v.select]
            
    # back to whatever mode we were in
    bpy.ops.object.mode_set(mode=mode)
    
    # select or unselect the respective fcurves
    for fcurve in o.data.animation_data.action.fcurves:
        vNumber = int(fcurve.data_path[9:-4])
        if vNumber not in selectedVerts:
            fcurve.hide = True
        else:
            fcurve.hide = False
            
def hide_unselected_curve_fcurves(o):
    
    - get all selected vertices
    - we need to switch from Edit mode to Object mode so the selection gets updated
    mode = bpy.context.active_object.mode
    bpy.ops.object.mode_set(mode='OBJECT')

    i = 0
    selectedPoints = []
    for point in bpy.context.active_object.data.splines[0].bezier_points:
        if point.select_control_point:
            selectedPoints.append(i)
        i = i + 1
            
    # back to whatever mode we were in
    bpy.ops.object.mode_set(mode=mode)
    
    # select or unselect the respective fcurves
    for fcurve in o.data.animation_data.action.fcurves:
        vNumber = int(fcurve.data_path.split('.')[1][14:-1])
        if vNumber not in selectedPoints:
            fcurve.hide = True
        else:
            fcurve.hide = False

o = bpy.context.object
#hide_unselected_vertex_fcurves(o)
hide_unselected_curve_fcurves(o)

Hello @robs_pangolin,
thanks for the report and workaround. This isn’t specific to AnimAll, but a known limitation of Blender’s animation system, which isn’t normally used to animate individual mesh (etc.) components. I don’t know if it’s desirable to support this either, since many types of data would need to be checked.

Perhaps @dr.sybren has details on this? Could and should the dopesheet.show_only_selected filtering be made to work with new object data?

This is indeed a known limitation of the animation system. It would have to be implemented in the skip_fcurve_selected_data() function (see anim_filter.c).
