Actually most of Carrara’s built in patterns or noises have a “Transform” tab where you can adjust the scaling on whichever axis you need.
I was messing around with this, and made a shader which uses fractal noise, cellular and the scan-lines pattern, mixed with a gradient so that you can control where the scanlines start and stop,
it’s a bit rough,. and it’s not a good example of lighting, ...or modelling but it’s the shader I’m playing with..so it’ll do.
I think this shader is still kind of rough, and perhaps a bit too shiny reflective, but workable.
