System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.15

Blender Version
Broken: version: 3.2.2, branch: master, commit date: 2022-08-02 18:15, hash: bcfdb14560

Short description of error
When animating the bottom track in the NLA's new Fullstack tweak mode, and the top layer has a combine blend type, then it's not possible to add keyframes in the bottom track to the Quaternion rotation.
in the attached file the cube is also going crazy when I try to rotate it.

the console throws this Warning

Warning: Could not insert 1 keyframe(s) due to zero NLA influence, base value, or value remapping failed: OBCube.Quaternion Rotation for indices [0, ]

This issue was also mentioned in this page about NLA: Keyframe Remap Through Upper Strips
https://developer.blender.org/D10504
but I thought it's better to make a proper bug report for this issue.

Exact steps for others to reproduce the error
open the file nla_fullstack_combine_bug.blend
you should have a cube with two tracks/strips. bottom track should be already in full stack tweak mode.
Try to rotate and to add keyframe to the cube, also with and without auto keyframe.

Work arounds:

  • This problem occurs in the 3d viewport, but when adding keyframe to the attributes in the N-panel or properties it works ok.
  • Another work around is to use 'COMBINE' blend type instead of 'Replace' blend type in the bottom track as well

Are you just creating a report for it to be tracked as a known limitation as mentioned in the linked patch?
Or is it an actual bug in the operator added by the linked commit?

Experiencing same issue observed by @TalHershkovich and @Likkez-2: Auto-keyframe mode and using the 'I' shortcut in the viewport do not insert keyframes, but hovering over the rotation values in the Transform panel and pressing 'I' works. Appears to be different than the limitations mentioned in the linked commit, which are cases in which keyframing will fail entirely, while in this case the keyframes do actually insert successfully when using the shortcut over the values in the Transform panel.

I can reproduce the issue somewhat.

in the attached file the cube is also going crazy when I try to rotate it.

This I cannot reproduce.

it's not possible to add keyframes in the bottom track to the Quaternion rotation.

This I do see with the attached file. As soon as I press TAB twice (i.e. exit and then enter tweak mode) it works just fine, though. Maybe this was fixed in the mean time?

@TalHershkovich can you test this again to confirm, please?

Hi Guys,
Sorry for my late reply. Yes, the bug is still there, I've just tested it on 3.5

@dr.sybren Did you go into full stack evaluation tweak mode. This is an issue that is directly related to. it works ok with the old (lower stack) tweak mode.
The layers order should be also "replace" blend type in the base layer and "combine" on the second.

As Omar already asked, is this a bug report or a known limitation thats noted elsewhere?

Yes, it's a bug. It works ok when hovering the properties tab and adding keyframes from there. The issue happens only when adding this keyframes from the viewport or dopesheet.

@dr.sybren Did you go into full stack evaluation tweak mode. This is an issue that is directly related to. it works ok with the old (lower stack) tweak mode.

I'm a noob. That was the difference.

But even when I'm properly in full-stack tweak mode, I can't reproduce the cube going crazy with rotation (I tried with both the 'R' hotkey and the rotation gyzmo) and I don't get the "Warning: Could not insert 1 keyframe(s) ..." message either when I try to key the rotation.

Blender doesn't actually insert a keyframe either, and it does when you hover over the rotation props and press I, so this is indeed a bug.

I'm a noob. That was the difference.

That's exactly why tab should be the default hotkey for for fullstack evaluation. Most people don't even know it exists, and it's pretty important update for the nla. after this issue is fixed I really don't see any reason to keep the old tweak mode, but I guess that's for another discussion...

But even when I'm properly in full-stack tweak mode, I can't reproduce the cube going crazy with rotation

I also can't reproduce it anymore, maybe it's something that been fixed. This bug report is more then half year old, so I can't really remember why I've added this here, I guess maybe because both issues were related to quaternions.
However the current issue with quaternions should be pretty important fix for the nla
