Description

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.

box demo

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 : Confirm
  • Delete / Backspace / ctrl+T / Tab(twice) : Cancel
  • M : Toggle Linear and Spline mode at any moment (disable autoswap on first use)
  • 1-9 top row number : Shortcut to subdivide box
  • Ctrl + 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

Todo:

  • Find a way to detect other modal to use ESC key for cancelling when only one running
  • target meshes
