Vertices being left behind even though they are in the deform cage...

Here is a picture of the mesh I wish to deform being selected and the deform cage.



The problem I have is that once bound, when the cage is deeformed, there is always a couple of vertices that are left behind…

Like this.



They are inside the cage deform, but whatever I do, they still stray behind…
I tried increasing the resolution of the cage by adding loop edges in the thigh region.
I tried increasing precision (my PC crashed at 8).

:spin: I’m at a loss as to what I could do next… I suspect the fact the thigh being very close to each other might be the reason for this but apart from making the model with legs apart maori haka style, I have to find a way around…
