**System Information** Operating system: Windows-10-10.0.18362-SP0 64 Bits Graphics card: NVIDIA GeForce GTX TITAN X/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.77 **Blender Version** Broken: version: 2.93.1, branch: master, commit date: 2021-06-22 05:57, hash: `rB1b8d33b18c2f` Worked: (newest version of Blender that worked as expected) **Short description of error** A grease pencil object can contain different "draw" layers. I assign a "lattice" modifier to the grease pencil object targeting the specific layer I want to deform. All works as expected, you can manipulate the lattice and the grease pencil layer in the grease pencil object, deforms. If you do this same method but using a MASKED layer (i.e: an eyelid masked by an eyeball layer in a character), the lattice modifier doesn't work in LOCAL SPACE, it seems it remains working in global space. I parented the lattice to be child of an eyelid bone, to see if that fixed the issue, but to no avail. **Exact steps for others to reproduce the error** video showing the problem: https://streamable.com/9ep14x Test File: {F10227783}

In sample file, deformation is simplified to moving all vertices. Here is original file, where actual deformation occurs, but I think relationships could be optimized a bit: {F10227783} **Exact steps for others to reproduce the error** {F10229172} # Open file # Move "handle" bone - works as expected # Move "base" bone - not as expected
