Procedural Kintsugi Material

Breathe life and history into your models with this custom material inspired by 15th century Japanese kintsugi!

"Kintsugi (Japanese: 金継ぎ, lit. 'golden joinery'), also known as kintsukuroi (金繕い, "golden repair"), is the Japanese art of repairing broken pottery by mending the areas of breakage with urushi lacquer dusted or mixed with powdered gold, silver, or platinum. As a philosophy, it treats breakage and repair as part of the history of an object, rather than something to disguise." [Source]

This completely procedural material was designed to give you the most freedom possible. Whether you'd like to keep the traditional ceramic and gold look that inspired the material or customize it into something completely unique, you'll find infinite possibilities for self expression with this material!

The custom node group for this material has 31 different attributes you can customize to your needs. Each setting is clearly labeled and includes a brief description on hover. You can find a complete description of each attribute at the bottom of this product page!

As an example: the "Pattern Randomizer" attribute allows you to randomize the cracks pattern to find the perfect fit for your model.

This custom material is also asset browser ready! Simply save the Blender file in your existing library and tag the materials accordingly. I've also included 4 preset materials to use "as is" or as starting points for your own unique materials.

Finally, below are some example renders of the material in action! (All statue models are from threedscans.com and are not included in the purchase. They're free though, so go ahead and grab them for yourself!)

Below is a full list of all custom attributes and their descriptions:

All inputs can be controlled by images or other nodes if you'd like!

Base Material

• Base Color: Adjust the color of the base material.
• IOR: Adjust the IOR (reflectivity) of the base material.
• Metallic: Adjust how metallic the base material is. This will overwrite the IOR slider if set to 1.0
• Roughness: Adjust the roughness (reflectivity) of the base material.
• Large Bump Strength: Adjust to change the large bump of the base material. Higher numbers make a bumpier material.
• Large Bump Scale: Adjust to change the scale of the large bump on the base material.
• Detail Bump Strength: Adjust to change the detail bump of the base material. Higher numbers make a bumpier material.
• Detail Bump Scale: Adjust to change the scale of the detail bump on the base material.
• Splotchiness: Adjust the varied splotchiness of the base material. Lower values mean less splotchiness.
• AO Amount: Adjust the Ambient Occlusion on the base material. Higher values make the crevices darker.
• Subsurface Amount: Add Subsurface Scattering to the base material. This allows light to pass through and bounce around inside the model.
• Subsurface Color: Change the color of the light bouncing around inside the base material if Subsurface Scattering is enabled.
• Subsurface Scale: Adjust how deep the light is allowed to scatter inside of the base material. Requires a value greater than 0.0 in the Subsurface Amount to have any effect.
   

Cracks

• Pattern Randomizer: Adjust value to randomize the crack pattern.
• Pattern Scale: Adjust the overall scale of the crack pattern.
• Line Thickness: Adjust the thickness of the crack pattern. Lower numbers make the cracks thicker, larger numbers make the cracks thinner.
• Line Bump Strength: Adjust the depth of the edges around the crack pattern lines. Values between 0 and 1 may create a broken line effect. It's best to use either 1 or 0.
• Line Bump Scale: Adjust to change the scale of the bump inside the line bump area. Most useful for larger pattern scale values.
• Line Bump Waviness: Adjust to change the waviness of the line bump area. Most useful for larger pattern scale values.
• Line Bump Thickness: Adjust the thickness of the edges around the crack pattern lines. Higher numbers make the bump edge thinner.
• Line Shadow Strength: Adjust the strength of the dark shading found around the cracks pattern.
• Line Shadow Thickness: Adjust the thickness of the dark shading found around the cracks pattern. Higher values make the shading thinner.
• Location: Adjust the location of the cracks. In general the X and Y sliders work best (though this is dependent on the orientation of your model).
• Rotation: Adjust the rotation of the crack pattern. The Z rotation works best (though this is dependent on the orientation of your model).
• Base Color: The base color of the cracks.
• Edge Tint Color: The edge tint color of the cracks. Primarily effects the look at sheer angles. White will give a neutral result if the cracks are a non-metallic material.
• Metallic: Adjust how metallic the cracks are. This will overwrite the IOR slider if set to 1.0
• IOR: Adjust the IOR of the cracks material. This slider is overwritten by the Metallic slider if it's set to 1.0
• Roughness: Adjust the roughness of the cracks material.
• Emission Strength: Increase the strength of the emissive light coming from the cracks material.
• Emission Color: Change the color of the emission coming from the cracks material. Requires a value greater than 0.0 in the Emission Strength to have any effect.
