Applies Gaussian blur. It will try to smooth the Height Map to have a similar average value according to the Blur Size.

Notes
We’ll start by creating a Voronoi Noise node and setting the Noise Type to Voronoi Index. This gives us flat regions with a single value across each region, which we can isolate using a Select Mask.
This mask defines the area where the pattern should appear. To smooth the boundary, we first blur the Voronoi noise with the Blur node, then reselect our region. Finally, we use Apply Mask to ensure that no values appear outside the selected area.
With our masked zone in place, we can use a Function node to generate the desired pattern and combine it with the Apply Mask node.
To break up uniformity, we then apply some warping to the entire pattern using the Warp node.
