yes, I found also some usable melee anims, but the begin/end are not looping properly, maybe good with other additional transitional anims, which is hard to find...

it is by Truebones (posted here stuff earlier), you can buy it in an enhanced pack in fbx format but it is really unclear for me what extra he offers. I asked him at UE4 forum but the answer is short and not descriptive at all...
