hi
everything is perfect for me except the wire
for some reason it doesn't show the wires of mesh when I activate it
It's in the weight paint context overlays now.
***Edit*** just realized this is the 4.2 version that Wayne is using. He covers these setting in https://cgcookie.com/lessons/07-weight-painting-overview around 9:20 and points out that he prefers the wire overlay that Martin pointed to.
