i need to get this oil streaking effect. I know there are a few procedurals that create circular patterns but i need these pararrel lines of different thicknesses and in different clusters etc. Its not the colour as that should be easier enough. its the white lines that are running vertical. i have tired to make lines and use a directional warp but i cant get the randomness and the different thicknesses. any help would be amazing.

Hello @defaultcga33rhbozw7, You can plug an Anisotropic noise node into a Quantize grayscale node. The former will generate lines of random grayscale values, while the latter will reduce the overall palette, which will merge some lines together and thus generate the randomness in line thickness. Connect the result to an Directional warp with a high Intensity value – i.e. beyond the default soft range, by manually editing the numerical value. This is the result of the example graph above.

I hope this is helpful! Feel free to get back to me in this thread if you need further advice.
