play fbx animation in specific time

i use unreal for rendering
i import a human body with animation in unreal

i wanna play that animation in specific time

i use sequencer , is it any chance in sequencer section to play fbx animation in specific time ?

You should be able to import the fbx animation which will create a skeletal animation asset. Then, add the skeletal mesh asset to sequencer and add the skeletal animation to a track as described here:

The animation should match in frames/times that you authored it in. Or, am I misunderstanding your question?
