Animation works in sequencer but not in render

Hi All,

I’m relatively new to Unreal and I’m currently working on an animatic to lay out my shots ahead of bringing in my final characters and assets. I’m using Manny and creating simple animations in sequencer so I have some timings. Every so often the animations I’ve keyframed with Manny won’t render even though they play fine in sequencer. The camera moves and other assets render, just not the animations. I can’t seem to fix the problem and it doesn’t always happen so not sure what’s causing it. Any ideas are welcome.

Thanks.
