PROBLEM with hand animation and switching to third person camera

Hello. I’ve been following this tutorial : http://shootertutorial.com/2015/06/04/add-fpp-arms-and-tpp-mesh-to-your-character/.

When I press play, I can see my hands. But they are not animated. When I press H, to swithc to the camera, I cna see my character but I cna’t turn him around. He is also not animated.

I hope someone can find a solution. If you need any screenshots or my project file, just write it.

Can you share some screenshot in blueprints?

Sure, all of them?

Places related to the hand.

here are the ones

It is very difficult to find a solution like this. Because there can be many reasons. But I think the problem is caused by blend space.

okay, and how can i solve it? do you want the project to test it?
