Rigging problem - weird issue !!!

Hello all :slight_smile:

I was rigging my character as always , i’m still a little new into rig but i understand it , anyway very weird problem happend that just the face when i rig it isnt affect by degrees , i mean if i even put a very small value like 0.01 into a vert on the face it act like 1.0 , its really weird because the rest of the body act normally , and the face connected to the boddy , i try to link one vert from the face to another bone and it act the weird way again so the problem from the verts not the bons from what i understande

please if you know what the problem let me know too :slight_smile:

waitting for the answare
