Hi Robert,
I have tried to make a simple file, but it is a bit complicated. I have link and make override of a character with armature, then make a simple animation.

  1. Unzip the attached file: " nla for override armature"
  2. Open the file: "Open this one".
  3. Select the cut strip and press tab to enter edit mode of the animation.
  4. Press tab again to exit editing the animation.
  5. Problem: the strip is no longer cut; the whole animation length appear in the track.
    We have to cut again, which is undesirable.
    Thanks

Editing of animation data with library overrides is still work in progress. I believe at this point in time it is expected that this doesn't fully work yet. I'll merge this ticket into #72629 which is the task for this topic.

@mont29 I've investigated this issue before merging. The NLA is linked, not newly created based on the data from the library override, and the ToDo ticket states that editing of existing NLA tracks from linked data-blocks isn't supported yet. Therefore, based on the information provided in #72629, this feature seems to be planned but not implemented. Hence I merged the ticket.

I apologies if I have misunderstood the description in #72629 and this is indeed a bug.

think this is a bug yes, edit of things in overridden NLA currently are supposed to either work as expected, or not be possible (hence some operator poll function probably needs some updates here).

Hi,
Even if a New Nla strip is made on the overridden armature object in the main file, same issue happens.
Thanks

@mont29 That's a good point. It looks like I was generally wrong with my initial assessment though and the problem is unrelated to library overrides.

@amshiv You're right. However, it seems that the problem of the strip returning to its original length appears to be completely unrelated to library overrides. I could reproduce the same behavior by creating a keyframe animation and performing the steps you've described in the same file. After the second tab it returns to its original length. Can you confirm this is the case for you as well?

While investigating this issue I've found another problem that will get a separate ticket on Monday. Deleting the NLA track and then expanding the hierarchy in the Outliner, results in a use-after-free according to ASAN.

  • Select the NLA track in the OPen this one.blend and delete it ({key del})
  • In the Outliner expand the hierarchy Cube > Armature > Animation > NLA Tracks.

However, it seems that the problem of the strip returning to its original length appears to be completely unrelated to library overrides. I could reproduce the same behavior by creating a keyframe animation and performing the steps you've described in the same file. After the second tab it returns to its original length. Can you confirm this is the case for you as well? ---- While investigating this issue I've found another problem that will get a separate ticket on Monday. Deleting the NLA track and then expanding the hierarchy in the Outliner, results in a use-after-free according to ASAN. - Select the NLA track in the `OPen this one.blend` and delete it ({key del}) - In the Outliner expand the hierarchy *Cube > Armature > Animation > NLA Tracks*. ```lines ## 3185==ERROR: AddressSanitizer: heap-use-after-free on address 0x60b0005ced50 at pc 0x00001704cf5f bp 0x7fffffffa460 sp 0x7fffffffa450 READ of size 1 at 0x60b0005ced50 thread T0 -

The length syncing behavior is not a bug ( https://wiki.blender.org/wiki/Reference/Release_Notes/2.92/Animation-Rigging#NLA specifically 6074636387 ) and recently made to be the default. However, splitting strips did not disable the Sync Length behavior and will soon be fixed.

OMG, it was that simple. Just had to uncheck the sync length.
Now its works.
Thanks a lot, Wayde Moss

While investigating this issue I've found another problem that will get a separate ticket on Monday

This one was fixed by b4530deec4

For the rest, we now have D10168: Fix #84486: Nla Disable "Sync Length" After Split, will set status to Confirmed though.
