Try using the “PLAY_MONTAGE” node, which is slightly different.
And hook up the MESH into the IN_SKELETAL_COMPONENT.
Also, I can’t recall, but does the Paragon mesh have a MESH and BODY skeletal reference, or just MESH?
(ps: I THINK you need to GET_REFENCE_TO_SELF to use that “Play_Anim_Montage” node, but don’t quote me on that. There’s so much to remember with this program.)
