Lattice with blendshapes problem

Hi I have a very simple character (box-like) and I attached to him a lattice and also some blendshapes. I also created clusters to control lattice points and then all parent them to a central circle curve to move the hole character. The problem is that when I translate or rotate the character and use blendshapes the vertices of the character trying to match the place of the blendshapes meshes.I tried to fix it from inputs hierarchy but the problem remains.
Please help.

One possibility is that you created the blend shapes as World space targets? They should be Local in most cases, certainly for something like this they'd need to be.

Also keep an eye out for double transform issues, I would most likely apply the lattice deformation to the main mesh as a blend shape (apply it to a duplicate of the mesh and leave it connected), I'd also use controllers local positions to drive the lattice clusters, just so I could leave that whole setup at world zero and just pipe the deformations through via the blendshape.

Lots of ways to approach it of course, that's just my typical approach right now for this kind of thing. It keeps things nice and simple to just have a blend shape deformer driving the final mesh for me and makes it easy to add/change things around.

Thank you very much Horganovski, I did a quick test with your method and works great.
Much appreciated!
