Hello everyone
I get this weird behavior when I move my character’s hand for pointing to a target:
I tried different ways like query for button down in Update. Store the result in a bool and use that for game logic. Clear it at the end of FixedUpdateNetwork. And using Fusion’s network input with NetworkButtons.
I’m not using animations because the hand must be pointed towards different targets.
Here is how I’m doing it:
I love those animation glitches! I’ve seen them all, still makes me laugh every time. 
I suppose you don’t have an Animator component on that game object? If not, you’ll need that. Maybe that’s it. If not, perhaps the Avatar in the FBX importer needs to be set up as well. In any case make sure regular animations work normally, then you should be able to move the bones around. Provided the IK system is enabled (which should be the default).
I’m not an animation expert, I just play with these every time all over again and there’s always something askew. Don’t give up. 
Oh and … setting rotations directly from euler angles. Not sure but this may lead to incorrect rotations. Consider that a fingertip rotated to 5 degrees is quite different than rotating it the other way to -355 degrees … because the rest also rotates along with it, so that would effectively break a couple bones and snap all the fingers tendons in a real human being.

@CodeSmile Thanks a lot for the response I really appreciate it!
Yes the character doesn’t have any Animator component because there will be 12 players in my game and the character should be able to point his hand to each player and I found this way of doing it is the best, maybe?!
But the problem is I get those glitches only when I’m connected to photon fusion, never saw them in offline mode or even online mode using photon PUN.
Should I use a simple forward pointing animation then use animation rigging to edit that animation?
Ok I solved it, it was just about Fusion components and the interpolation stuff
