Hello friends

I start testing accuring for full body character rig but after many tested i have problem to rigging a fingers of the my robot hands
I am very satisfied with the neck rig, as you can see in the pictures the neck and pipes work very well, but not work well with fingers.
Actually, the body of this model is from Adam's model in Unity!  I deleted the previous rig and also vertex group on Blender.
I try my best to place finger rigging dot on the correct place ..  I dont know maybe I place on the wrong place !
Can anyone help me in this matter, thank you in advance.



(  The fingers are separate like robot fingers - but merged as hand part )
