I'm having trouble with my lattices getting deleted when I try to delete history.
Of course, I should be using Delete Non-Deformer History, but I'm finding situations where that is not enough (for some reason I cannot rename color or UV sets while a lattice is affecting a mesh).
I have tried using the Relationship Editor for Deformer Sets to add/remove meshes from the lattices, but even if a mesh is removed from the deformer set, when i delete history on the mesh the lattice gets deleted as well.
In the hypergraph display, the ffd node connected to my mesh is gray and I cannot manually unhook the node.
My work around is to duplicate the lattice with no input connection, delete history on my mesh, and then add the mesh to the newly duplicated lattices deformer set.
The other workaround solution I've found is add a dummy object such as a poly cube to the deformer set so the lattice is saved when I delete history on the original mesh the lattice was deforming.
thanks.
