Blender addon - Modal that create temporary deforming rectangle around selected GP points.
Note : Since Blender 2.91, Box deform
is integrated in the official addon Grease Pencil Tools
bundled in Blender. You just have to activate it.

I first created this as a prototype following my request post : Cage deform active tool for grease pencil
Turns out this works really well as it is, so I added some shortcuts for usability and voilà !
Developed for Grease pencil, (mesh might be supported in the future.)
Example with lattice subdiv and spline deformations.
How to use: (same tutorial in addon preferences)
Use the shortcut Ctrl + T
in available modes
The lattice box is generated facing your view so be sure to face canvas to avoid unintentional anamorphosis offset
Then use following shortcuts (also displayed in topbar):
Modes and deformation target:
- Object mode : The whole GP object is deformed
- GPencil Edit mode : Deform Selected points
- Gpencil Paint : Deform last Strokes
Shortcuts (also displayed in topbar):
Spacebar
/Enter
: ConfirmDelete
/Backspace
/ctrl+T
/Tab
(twice) : CancelM
: Toggle Linear and Spline mode at any moment (disable autoswap on first use)1-9 top row number
: Shortcut to subdivide boxCtrl + arrows-keys
: Subdivide the box incrementally in individual X/Y axis
Notes :
If you return in box deform after applying with a ctrl+Z, you need to hit ctrl+T again to revive the modal.
A cancel warning will be displayed the first time you hit Tab (to avoid mis-canceling)
Multiframe edit selection works but you will only see the current frame during the modal
- Find a way to detect other modal to use
ESC
key for cancelling when only one running - target meshes
