There is probably a simple answer to my problem so here goes:

I've selected a load of cv's and applied a lattice deformer to them. The lattice appears and works fine. However, say for example I missed a cv that was meant to for the lattice. Well I need to add that cv to the lattice, but no matter what I do I can't seem to add any more cv's to the lattice, although I can remove them easily using paint set membership tool. I must be something wrong!

Please help...

regards,

Jim.
