This is a simple shader node group that breaks up the visual repetition of tiled textures. It uses a Voronoi texture's cell colors to apply a random translation and/or rotation to an image texture's vector input to produce an irregular pattern.
I primarily made it for landscape materials. The cells' borders are still sharp, so certain materials, like bricks, wood, or fabric, will not look good.
Brilliant! We need this in UE5 as well!
