Procedural scratch with directional control
polycounter lvl 6
Hi,
This is kind of a challenge: I am looking for a way to generate scratch/worn similar to the effect on Tracer's leather jacket:
I already know how to generate the seam, and the wavy color fade around seam, and now I have to simulate the sharp scratch that extends vertically along the seam.
I am aim to do this completely in Substance Designer (as a material), so no actual handpainting or SP physics simulation allowed.
My current idea: somehow achieve this using a Tile Sampler node. Create a vector map for the seam, then you tell SD, apply rotation on the scratch shape so it align vertically to the seam, then randomize the shape.
But alas, while it works, I can't find a good way to generate that scratch shape. What would be your suggestion?
(PS: My progress so far, using only base color and roughness, I am going for a stylized look)
With scratch (basic shape, obviously look wrong)

You can try using a softened anisotropic noise warped with another noise of your taste. And then isolate nicer looking shapes by histogram scan etc.
