so I'm modeling a katana, and I would like to give it a proper "Damascus" style to the blade, and I was wondering if it's possible to achieve this in a way that doesn't involve me opening GIMP/Photoshop.
So my questions are:
How to "mask out" the black so I can control it, and apply the Principaled on top of let's say a brushed metal shader.
Is there a way I can make the noise/musgrave/voronoi start in stripes and then go wavy? Maybe aWave texture and use a ramp to fade them?
Thanks for any input!
