thx raziel,
as martin said didn’t know about Collada working and didn’t even think to try it.
and I would have never thought to exclude those bone mappings, so thanks for that info as well.
I really like how MH is evolving, the future possibilities are unlimited. 
& absolutely agree the Blender 2.74 exporter is way better now.
note: btw, don’t remember the circumstances but had to re-skin a MH model in blender so I used rigify which gave weird results until I excluded the IK bones in the UE4 skeleton. than worked like a charm, just in case this helps anyone.
