Thankyou for your reply, My issue with the animations completely relates to using another skeleton and retargeting to it. In the retargeting process the vertical movement is lost. As you have said its not a root motion issue but perhaps is a scale import issue from my end?
However the error i get on startup is most certainly there. In PIE it works as expected, my worry is that if unreal is throwing up an error, it won’t compile.
I will try re-migration (not a big deal), but as i said it works perfectly in PIE unreal throws up the warning anyway.
I’ll let you know what i come up with.
