**I’m getting visible hexagonal / circular artifacts when painting landscape layers.**

I’m also sharing a screenshot of my landscape material for reference. I’m a bit of a newbie with landscape materials, but from what I can tell this doesn’t seem to be an issue with the material functions themselves — when I fill the entire landscape with a single material, everything looks fine.

The artifacts only appear when I start **blending / painting multiple materials**. Additionally, the **grass layer doesn’t seem to work when painting** , even though the grass material itself previews correctly in the Content Browser.

Any insight or suggested workflows would be greatly appreciated.
