We have a fairly complex script that has external side effects outside of Blender’s Property System. These external side effects are triggered by Operators and Property update callbacks.
Blender’s Undo/Redo system can make Blender’s internal properties inconsistent with these external side effects. Is there any way to either:
- Disable Undo/Redo on specific Blender Properties or Property Groups?
- Trap the Undo and Redo so we can perform the undo/redo operations on our external data?
The Global Undo option in User Preferences / Editing works for this, but it disables undo/redo throughout Blender. We’d just like to disable it for the properties and groups associated with the external side effects.
Thanks in advance for an answer … either way.
