I want to use a Voronoi 3D Cell scalar noise as a base for my terrain.
It works fine but I would like to smooth the sharp edges and remove the artifact-structures on the vertical surfaces.
Any ideas ?
Thx DJ

Good question! I worked on that for a while but couldn't get a satisfying result.
Have you tried either of the erosion operators?
Thank you, buzzzzz1.
IT WORKS!
I tried smooth and erode:

wow that's pretty impressive, interesting how similar both operators are. These will only work on heightfields yes?

But how do you do it without converting it to a heightfield?
This could be interesting.
You have to convert it to a heightfield, afterwards you re-convert it to a shader:

And since you have a fractal noise to base the heightfield on, you can make the heightfield as large as you want without loosing any detail...
Yes you can soften the edges of the Voronoi cells without converting to a height field.
Not perfect but here's a method I posted last year:
