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.
#Karma

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.

This is my file. Thank you.

I tried it in UE4.7.6 in win64. It crashed.

Thank you.
But I don't know what is ‘fetch cook log’ button. Do you know where I can find it? I am sorry.
I used UE4.8 in win64 and it caused such problem. I also tried it in UE4.7 in MAC and it worked well, although I can't see the texture.
I downloaded my UE4.8 from gitbhub and built it in my computer. I also use other plugins in UE4.8.
Maybe my project is useful for detecting the problem if it's useful.
Thank you.
