hello

How can I do, in a procedural node like voronoi, only what is in the red circle in the image to create a procedural brush?

thanks

Set up Voronoi as your TEXTURE for your brush in the Texture Paint Workspace

hello

I’m sorry, I didn’t describe exactly what I want.

I want to do what I described in: shader editor with procedural maps.
I don’t want to create a brush.

I want to make a hole in the texture with the fragment of the voronoi that is in the red circle.

it’s possible ?

thanks

Hi there :blush:

You can create a Gradient texture, set it to be a circle. With vector math add or mapping, you should be able to move the white circle around. Use a Math - Greater than to make the circle sharp or a Mix - Colour dodge / burn (cannot remember which lol) to play with the falloff (I can show you later, not at my rig now).
You can also distort the circle on the vector line with a noise texture.

So this spot will be your mask. You place it over the desired place upon the voronoi and then multiply or use as a Fac in a Mix node to make all else black.

Hope I understood you correctly

Cheers!
