System Information
Operating system: Windows 11
Graphics card: GTX 1080

Blender Version
Broken: 3.3
Worked: None

Short description of error
When using Blender with an OSC input and automatic keyframes, no keyframes are generated.

Exact steps for others to reproduce the error
Use an OSC plugin like AddRoutes. Stream data from an OSC device like an iPhone to control rotation of an object. This all works completely normally and flawlessly. The issue comes into play when I try to use the Blender automatic keyframe feature to record the frame-by-frame changes in object rotation that are being streamed to Blender from my phone. I can see the updated rotation in the viewport, but no new keyframes are created.

@dr.sybren hi, is there something to be added in blender code to support the auto-keyframe with OSC input or is it an add-on specific issue? Any idea?
I've not tested this myself. Will try today itself.

So I have found a way within the add-on to automatically record keyframes and it is working for me, but I am still wondering why it wasn’t possible before with the function built into Blender. The rotation values were constantly changing, but the automatic keyframes were not being generated at all.

I'm assuming OSC stands for Open Sound Control -- might be nice to put that in the task description if that's indeed what's meant. I also don't see any OSC add-on bundled with Blender; if this is about a third-party add-on, that info would also be much appreciated.

The auto-keying system in Blender is not that automatic. An add-on that modifies object/bone transforms doesn't get auto-keying for free, unfortunately. Auto-keying needs to be explicitly added to any code that manipulates data.

Good.

You need to be a bit more specific than "the function", because Blender has loads of them.

@dr.sybren , yes, OSC stands for Open Sound Control.
And yes, third party add-on is involved here: AddRoutes.
Perhaps I was too quick to tag you here because I wasn't sure whether its an add-on or a core animation code is preventing the keyframe creation.

Your response clarified my doubt :)
Guess we can close this report

Yup, this should be discussed with the add-on author, then. It's not a bug in Blender.
