I have this procedural noisy dots texture and I would like to thicken the dots outward.

enter image description here

I am looking to create an effect where the dots would expand similar to how you can grow a selection in GIMP or photoshop and then fill the selection with black. enter image description here

This is the desired effect. Thanks for any help. enter image description here

What kind of dots are you making? If a "swiss cheese" effect would suit you, a Voronoi texture works quite well. If you like, you can use a Power (math) node to control the size of the dots.

    $\begingroup$ @GiantCowFilms Multiply will brighten/darken everything. Power will make bright values brighter and dark values darker. $\endgroup$ Commented Jun 2, 2018 at 14:57
