Overview

The Wood Cracker Tool is a geometry nodes-based asset that allows you to create realistic wood fractures and breaks. It uses customizable cutting planes to simulate how wood would naturally split or crack.

Parameters

Main Controls

• Both Sides: Toggle to enable fracturing on both sides of the object
• Left Side / Right Side: Individual control sections for each side of the fracture

Cutting Plane Controls (Per Side)

• Preview Cutting Plane: Toggle to visualize the cutting plane in the viewport
• Cutting Plane Size: Set the dimensions of the cutting plane (in meters)
• Cutting Plane Transform:
  • X: Horizontal position of the cutting plane
  • Y: Vertical position of the cutting plane
  • Z: Depth position of the cutting plane
• Cutting Plane Rotation:
  • X: Rotation around X axis (in degrees)
  • Y: Rotation around Y axis (in degrees)
  • Z: Rotation around Z axis (in degrees)
• Cutting Plane Resolution: Controls the detail level of the cutting plane (higher values create more detailed fractures)

Noise Controls (Per Side)

• Cutting Plane Noise Direction: 3D vector controlling the primary direction of the noise pattern
• Cutting Plane Noise Scale: Adjusts the overall size of the noise pattern (higher values create larger features)
• Cutting Plane Noise Detail: Controls the complexity of the noise pattern (higher values create more intricate fractures)
• Cutting Plane Noise Offset: Shifts the noise pattern along the cutting plane

Materials

• Wood Material: Slot to assign the material that will be applied to the fractured wood surfaces

How to Use

1. Add to Object: Apply the Wood Cracker Tool to your object
2. Configure Sides: Choose whether to use one or both cutting planes
3. Position Cutting Planes: Adjust the Transform and Rotation values to position your cuts
4. Adjust Noise Parameters: Fine-tune the fracture appearance using the noise controls
5. Assign Materials: Add your wood material to the material slot

Requirements

• Blender 4.2 or higher (has not been tested in older versions)
• Basic understanding of Blender's geometry nodes system
