Material Time in Sequencer

Is there a way to keep things like sprite sheets in sync with sequencer time?

Time based materials work on engine time, but how can I control their progress in sequencer so that they are not always playing?

what if you try a scalar value instead of time, and just key that in sequencer?

Of coarse, so simple! It works but not with the values I would have expected: 0-10 for a 20 second animation looks about correct, I expected it would be more like 0-480 @ 24 fps. All the same, this should do the trick.

Thanks for the suggestion!
