I made an animation of a peacock closing its tail, using feather nodes to make feathers, using vellum node to solve, but unfortunately not all parts of the feathers to solve, and finally using Karma to render.

I hope to use motionclipextractpose node, but I encounter this problem.
Is there anyone can help me?
Many thanks.

And this time I used UE4.7.5. I met the same problem as UE4.8.1. I guess maybe it‘s my computer's environment's problem.
