16 ratings

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

It's difficult to overestimate how cracks affect the overall appearance of an object or a scene. Cracks can be found everywhere, from pavement stones to ancient ruins. Despite this, it is one of the most difficult things to model. Until now!

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): Create cracks and displace cracked objects afterward.

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.

Physically Based Grounding: Press Ctrl+Shift+LMB to drop the cracked piece to the ground. Note that this feature uses rigid body simulation; don't forget to add ground object to your scene with passive rigid body settings.

P.S. If you didn't see the cracked piece after operation, it means it flew away during the simulation. Press ctrl+Z to undo and try a different angle for the crack, or check for obstructed objects nearby.
