Any way to find verts that have no bone weights?

I’m importing some stuff that I made into Unity and it complains that some of the vertices have no bone weights assigned. It’s pretty easy to see the verts that are affected by a bone, but how would I find any verts in my mesh that aren’t weighted to a bone?

grab your armature in pose mode and drag it somewhere. any verts that get left behind can be considered to be un-assigned :smiley:

And there they are. Thanks!
