I'm completely new to texturing. Water stains are wide st the top then converge in. And underneath the stains, has to be a concrete texture. Is it a possible to achieve through procedural texturing? If so, which nodes should I use? I could also just use an image, but I'm having trouble finding images that extend as long as I need them to be.
Here is the texture i'm inspired by
This reference image is stylized, but I would like to make a bit of a more realistic texture.
