I have a basic walk cycle going- it's three steps over 34 frames. I've applied post-infinity and I playblasted the animation over 100 frames or so.

Trouble is, the playblast only shows those three steps!

I even changed the timeslider and playblasted from frame 439 to 500-> i.e. well away from the first 34 frames and it's the same thing->>> it only shows three steps. It's so weird.

Help please?
