Hey i ran into a similar problem, he is just stuck in a T pose, mesh is not animating in the sequence
My character stays in a T pose within the animation sequencer, this happens when i use certain animations, not all of them. Some would animate but this one wont, Anyone understand why this is happening?
Also i do notice for the ones that work, i log off/ log back on and then it stops working, i would have to delete the UASSET file and reimport it into my content folder and then it works. Is there some kind of plug in that i am missing or is it unreal engine 5 thats the issue? do i wait for updates? not sure if this is a common issue going on
