Is there the possibility, that I can set up a transition between say Walk and Idle Anim in the Sequencer itself without having an extra animation?
Other wise the animations look cut. Please tell me if there is a way to do that 
i have the same problem 
maybe the only method is using cuts…
this is a video that i made with sequencer where i used cuts - YouTube
Afaik there is no way to blend animations in Sequence, I wish to be proven wrong
