Summary:
Multiple Scene Strip in Sequencer, bad scrubbing for armatures in viewport
Detailed description
Hi!

I have a little trick to get ghost poses in animation, three Scene strips with +1 frame offset and different colors, see "ghostposes.png" on attachments
So useful in animation spacing and timing feedback.

Issue:
- Open "scrub.blend"
- Scrub back and forth the animation for a while
Result: During Scrubbing the animation "jumps" in 3D viewport

This Issue seems that only happen with armatures in the scene not if only are meshes

It would be nice "autorefresh" or "force refresh" option/button in sequencer editor, so when you are posing in 3D view to get a immediate feedback,
now you can scrub again to see the results.

  • This should be fixed now, thanks for the report!

    The scene wasn't updated properly to it's original frame after rendering the offset frames, but now it's always updated if the drawn frames differ from the original. This makes the updating a little a bit slower since there's an extra scene update, but now it at least works consistently.

    The current dependency graph isn't really well suited to other than object-object dependencies, so the "autorefresh" functionality for the sequencer isn't really currently possible nicely. However it will most probably be implemented once the dependency code gets updated at some point.

    About autorefresh, do you know if is possible assign a hotkey to "Refresh sequencer" thats works when you press the ShorKey in 3D view?

  • There's currently no hotkey assigned to "refresh sequencer" operator at all, but even if there was it would only work inside the sequencer view as far as I know.

    You could of course define a new window level operator that would call the sequencer refresh function, but that's not really acceptable for general usage as it's not clear what the hotkey applies to then.
