On a particular project, the lattice I was using was deforming four planar mapped textures along with my geometry, so I couldn't just make the deformation permanent and render without the lattice; the textures need the deformation lattice, too.

So I tried running Burn UV on the object with planar map below the lattice. I then went up a level and grouped the lattice with the mesh and converted to polymesh. This deleted all my textures, which was a bit of trouble, but when I reapplied them with UV mapping, they followed the deformation of the mesh perfectly, with no lattice required.

On some projects, this can make a huge difference in render speed, and may well be worth the little extra time it takes to reapply textures after the conversion.
