Patchwork is a Blender extension. Install the .zip through Edit > Preferences > Add-ons / Get Extensions > Install from Disk and enable it. Open a Shader Editor, select a material and press N to find the Patchwork tab in the sidebar.

Once a material is wrapped, the Texture-Pattern dropdown at the top of the N-panel sets the cell shape: Voronoi, Noise, Gabor, Blocks or Rings. Switch freely — the change applies to that material's wrapper live, no re-apply needed.

Select the Patchwork group node to reach its inputs. Cell Scale sets how many cells cover the UV, Random Rotation and Random Offset vary each cell, Noise Strength and Noise Detail break up the borders and Border Width with Edge Softness controls the transition. Set Bypass to 1 for a raw-texture A/B against the anti-tiled result.

Remove from Material dissolves the wrapper and restores your original Image Texture nodes in the main tree. Remove from All Materials clears every Patchwork group in the file and deletes the shared transform group when nothing else needs it.
