Cracker – Quick Hotkeys Guide
Cracker works on a single selected object only.
1. Quick Mode (Destructive)
- Select an object → press Ctrl + W (You can change this combination in the add-on’s Preferences)
- Cracker is active and a HUD appears with parameters
- G – Move
- R – Rotate
- Enter – Confirm
- Esc – Cancel
2. Circle UI Mode (Non-Destructive)
Gives more visual control with an on-screen circle interface. Recommended for non-uniform or complex objects — it lets you place Cracker more strategically exactly where you want.
Two ways to activate it:
- Use the Cracker Panel → click Add Cracker
- Or start in Quick Mode (Ctrl + W), then press Shift + Enter
Stomper – Quick Note
To work properly, each object you want to affect with Stomper must be a proper 3D object (not a flat, paper-thin plane) and have its Origin roughly in the center.
Cracks can deeply transform the aesthetics of any scene. Whether it's pavements or ancient relics, replicating these intricate details has always been daunting. With the Cracker add-on, turn the intricate process of crafting perfect cracks into a breeze. Why struggle when you can crack it with ease?
The Cracker add-on is a handy little tool for making cracks as easily as possible. Select an object, press Ctrl + w, adjust for the desired appearance, and apply. It's really that simple. You can now create cracks at the speed of thought!
the Glass Breaker tool v1.2 - Alt+Y
Press Alt+Y in Object mode and choose the Breaker tool. Adjust for desired look.
Note: For Glass Breaker, the object should be a flat surface with thickness (e.g., window glass). The front face must be a single polygon. Remember to Apply Scale before using.
the Glass Breaker tool v1.2 works only with Blender v3.4.0 or higher.
Can't brake round objects like Vase, Cups etc.

NOTE! The Cracker works with real geometry and can ruin your model (and it will), so please make a backup copy of an object or scene beforehand. (crucial for production environment)
