I'm trying to learn more about procedural textures, and I created a concrete texture loosely following a youtube tutorial. At the scale I worked at, it looked just like I wanted. However, when I tried to apply the texture at larger scales, pale stripes appear on the surface. It does not seem to be related to the mesh, but to something inherent in the texture.
Could someone tell me what went wrong here and how can fix it? Thank you in advance!
