Bastien Montagne (mont29) updated subscribers of T74207: Adding a mask modifier causes the shape key driver to fail..

The issue here is that the drivers gets evaluated by the depsgraph, using evaluated datablocks. And evaluated objects have evaluated obdata (like mesh) from modifier stack, which obviously have no shapekeys anymore (since those shapekey data would be completely invalid for the mesh generated by the modifiers most of the time).

Demeter Dzadik (Mets) added a comment to T73593: Drivers on hide_viewport and hide_render are unreliable, and throw warnings on linked-but-not-proxied objects..

I think I can still reproduce this issue, eg. changing the "Dress" property in hailey.blend above. q_q Do I re-open?

Sybren A. Stüvel (sybren) added a comment to T74000: Property controlled drivers not updating from python.

Is there a reason to move to the next frame?
As I understand the setting the current frame will also trigger an update.

Sybren A. Stüvel (sybren) closed T74000: Property controlled drivers not updating from python as Invalid.

That blend file (Food_Apple.blend) is set up incorrectly; the custom property is set on the Scene, but the driver is accessing it on the Object. I have corrected this in

.
The code also doesn't work with that blend file:

Mon, Feb 24, 4:49 PM · Data, Assets & I/O, Animation & Rigging, BF Blender
Bastien Montagne (mont29) triaged T66913: Issue with Undoing after using next/previous keyframe shortcut. as Low priority.

Note that we do not want time (i.e. animation data) to be re-evaluated on undo steps. think issue here is, transform values of the object stored in undo steps memfile are then the orig ones (from read data, matching first keyframe I guess).

Sybren A. Stüvel (sybren) changed the subtype of T50423: Adding new hook while in Edit mode breaks when trying to undo/redo the operator from "Bug" to "Known Issue".

The problem is that an action can either store an undo step for edit mode (which doesn't include things outside of edit mode, such as the pose bone properties) or it can store the entire scene in memory (which doesn't include edito mode data). Deleting a bone changes both sets of data, so it cannot be properly un-done with just one step. This is a limitation that needs proper design work to resolve.

Sybren A. Stüvel (sybren) renamed T64612: Pose Bone data is lost when undoing an Edit Bone deletion. from Bone's "Custom Object" (bone shape) is lost when undo-ing a bone deletion. to Pose Bone data is lost when undoing an Edit Bone deletion..

Sybren A. Stüvel (sybren) changed the subtype of T64612: Pose Bone data is lost when undoing an Edit Bone deletion. from "Bug" to "Known Issue".

I discussed this with @Bastien Montagne (mont29), and he said it's a known issue. The problem is that an action can either store an undo step for edit mode (which doesn't include things outside of edit mode, such as the pose bone properties) or it can store the entire scene in memory (which doesn't include edito mode data). Deleting a bone changes both sets of data, so it cannot be properly un-done with just one step. This is a limitation that needs proper design work to resolve.

Sybren A. Stüvel (sybren) added a comment to T64612: Pose Bone data is lost when undoing an Edit Bone deletion..

It looks like more than one undo step is recorded for the deletion of a bone. When I delete the bone and then Ctrl+Z twice I get the custom shape and the constraints back.

@Sidney Moraes Jr (mangojambo) That seems to be a different issue. Let's continue at T67232.

@Germano Cavalcante (mano-wii) This is not the same issue as T73051.

Hello. I was checking the related task and I see it is marked as resolved, but I did a simple test using today's build and the bug still there:

Sybren A. Stüvel (sybren) closed T63320: Mixing Bone Parent and Bone Relative Causes Object Offset as Invalid.

This is not a bug, but "simply" the way Blender works. Relative Parenting is an option that can be set per bone, and not separately for each child of that bone. I have added a note to the manual to clarify this.
