Is it possible to copy and paste vertex weight? Is it possible to copy the vertex weight from 1 vertex on a body mesh, then paste that weight onto ALL the vertex of a selection (basically an accessory that's joined to the body for the purpose of pasting vertex weight), instead of 1 vertex at a time (that would take forever for any object unless it's a cube or something)? I found a copy/paste vertex script by Ivo Grigull but it's only for very old Blender versions (pre-2.4.9).

Also, whenever I manually copy/paste vertex weight (one at a time, was testing it with a cube), then later separate the cube from the rest of the body by selecting all vertices on the cube and press P, the body would get completely distorted (stretched to infinity in all directions).



Anyone know how to paste vertex weight onto multiple vertices, as well as why my weight-pasting doesn't work at all?
In Weight Paint Mode you can set Weight by pressing Shift + K.


Toggle Vertex Selection Masking to select the vertices





Set the Weight (use @joshsanfelici technique to copy vertex value)
Press  Shift + K to set weight
