How to assign a specific weight to vertices? (instead of painting it) I was wondering that in the weight painting mode, how can I set a specific weight for a certain group of vertices instead of painting it over them?
Ah, I was fooling around and found an answer.


In the weight painting mode, use the Vertex selection masking for painting  V
Select wanted vertices for example with Circle select tool C
Set the wanted weight from Tool Shelf T
Weights -> Set Weight Shift+K




In addition, there's a useful addon for setting weight values:
