Broken: 2.70 #b66a954
Worked: None I could find

Short description of error

Any VSE strips that have drivers attached to values, play driver animation ok. But the same driver animation fails at render time.

Exact steps for others to reproduce the error

  1. Add a strip of audio or video or still image and attach a driver to a scene object.
  2. Animate the object with keyframes.
  3. Render out animation.

The animation does not get baked into animation drivers.

I have attached a .blend with an audio strip as an example.

Sorry here is the .blend file. I accidentally added the clean audio in the task. This file has the audio packed in.

Sorry I see now that there is an item number for this problem https://developer.blender.org/T39697

Strangely a search did not turn this up earlier. Also my problem is not using a "frame" call.

Joshua, I’ll let you decide whether to merge or not. :)

Merged T39697 into this one, since this one seems to refer more to the generic issue here than the other one does.

@Joshua Leung (aligorith), shall we consider this a bug or a TODO for the ongoing depsgraph project?

@Joshua Leung (aligorith), *poke*

Poking @Joshua Leung (aligorith) again ;). If we don't get a decision, I'll go ahead and close this as a todo.

Sergey Sharybin (sergey) changed the task status from Unknown Status to Unknown Status.May 26 2015, 6:36 PM

I'd consider this a TODO related to the depsgraph refactor project now. It'll be easier to support such situations there,
