3 Tools in 1 package. (New V1.7)

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!

  • Physics-Based Grounding: Automatically places cracked objects at ground level.
  • Instant Visual Feedback: See adjustments on your model in real-time.
  • Streamlined Workflow: Intuitive hotkeys speed up your process.
  • Stomper Tool (Ctrl + R): Rotate cracked objects to simulate the effect of impact.
  • Material Breaker (Alt + Y): Perfect for shattering windows.
  • Detail Control: Adjust crack detail on-the-fly with your mouse wheel.
  • Multiple Cracks: Hold 'Shift' when hitting 'Apply' to add another crack without separating the object.
  • Chip Off Function (Ctrl/Cmd): Want a piece chipped off? It's a click away.
  • Versatile Viewpoints: Operates from any angle - orthographic or perspective.
  • Customizable Cracks: Adjust rotation, noise scale, width, move, bend, and more.
  • Randomizer: Get unique cracks every time with random rotations and positions around an object's origin.
  • Cracked Surface Material: Choose a material for the cracked surface or leave it unassigned.

Physics-Based Grounding: To drop a cracked piece to the ground, press Ctrl+Shift+LMB. Remember, this feature leverages rigid body simulation, so always include a passive rigid body ground object in your scene.

P.S. If you can't locate the cracked piece post-operation, it likely went astray during the simulation. Simply press Ctrl+Z to undo, and then either adjust the crack angle or inspect for potential obstructions nearby.
