Replacement to remove a Mesh

Sometimes you will need a variant in another configuration to remove a mesh while active.

To remove the Armchair Mesh, simply add Mesh replacement: [armrest -> nothing] and the mesh will be removed.

Replace incorrect Mesh with correct one

After removing the armrest, we notice that our legs mesh is not correct. They are cut to fit the armrest.

To fix this, we can add another Mesh replacement: [legs -> legs no armrest]
