UE5.6 Sequencer Shift+V&U Issue

1.最新版本UE5.6 Sequencer > Expand/Collapse Nodes and Descendants（Shift+V）只能展开，无法折叠，请修复，UE5.5是正常的。（SequencerShift+V.mp4）

2.Keyed（U）功能启用后，在本来具有关键帧的Actor下添加新的轨道关键帧，新轨道会实时更新在过滤结果里，但是没有关键帧的Actor创建关键帧的时候，这个Actor本身不会出现在过滤结果，这似乎有点矛盾，请修复成实时刷新。（KeyedUpdate.mp4）

1.In the latest UE5.6 Sequencer, Expand/Collapse Nodes and Descendants (Shift+V) can only expand nodes but fails to collapse them. Please fix as UE5.5 functions normally. (SequencerShift+V.mp4)

2.When Keyed (U) is enabled:

Adding new track keyframes to an existing Actor with keyframes updates filter results in real-time.

However, when a keyframe is created for a new Actor without any keyframes, the Actor itself does not appear in filter results.

This behavior appears contradictory. Please implement real-time refresh consistency. (KeyedUpdate.mp4)

Hello [mention removed]​

Thank you for reaching out and bringing those issues to our attention.

I was able to replicate both.

I’ll make issue reports and share the links once I have them.

As a side note, I would like to let you know that the general recommendation is to report one issue per case.

I know it can be a bit of extra work, but it helps the dev team’s understanding of each case if it revolves around a single issue, especially when discussions get very long; it can become confusing if it branches.

It’s also important for the service metrics: multiple issues in one case negatively affect the perceived efficiency of the EPS service.

Thank you for your understanding.

All the best,

Hello [mention removed]​

Thank you again for reporting these issues.

I’ve made two JIRA reports to be added to the Unreal issue tracker website (https://issues.unrealengine.com).

Please note that Epic ultimately determines whether the issue will be made publicly accessible, and the process can take a few days; therefore, the tracking link may not be immediately accessible.

Once available, you will be able to track the resolution of the Expand/Collapse Nodes and Descendants (Shift+V) issue at Unreal Engine Issues and Bug Tracker (UE\-300120) and the resolution of the Keyed (U) issue at Unreal Engine Issues and Bug Tracker (UE\-300304\).

I’ll close the case, but feel free to reply if you have anything else to add.

All the best,
