"Bake Action..." bakes wrong on flat curves #82210

New Issue

System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce RTX 2070 with Max-Q Design/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2020-10-27 22:14, hash: 024b65b5e5

Short description of error
When using Bake Action with step of 1 (2, 3 etc) if a curve has a part that isnt moving (where the value holds in say 1 for 10 frames), then it only gets a key on the first one and last keyframe instead of every frame

Exact steps for others to reproduce the error

Insert a key in the default cube.

Create a curve like this (with at least 1 flat area where the value doesnt change)

In the 3d view, go to object > animation > bake action

Result obtained:

Result expected:

Thank you guys!, I understand if it was "intended" as a feature but that breaks the baking and we have the cleanup operators after all if we actually need this.

yeah i understand that, but is this INTENDED behaviour ? are you sure?

Let me guess it's running the clean channels operator after baking, should we just make this explicit and have a checkbox to "clean curves" ?
Explicit is better than implicit :)

Yes.

Also yes. but it's not bug technically.

I guess I can confirm if this have negative impact on your workflow and let module decide. It is easy to implement after all.

This is indeed not a bug, but nevertheless it's something that ought to be fixed (see yesterday's meeting notes ).
