Complex Anisotropic Texture

Post by Snowcarver » Fri Jul 24, 2020 3:34 pm

Hi, who knows, how to create such mtls?

UPD: My idea - modeling and shrinkwrapping real round, array it, separate and apply anisotropic mtl to each example. :D

You need a texture with the same pattern and add this texture in the roughness and bump slot of your metal shader.

Unfortunately, I cant get such seamless pattern. I have thought a kind of procedural trick exists.

There is a poliigon texture that will do just this.

I've only seen it used in cycles so I'm not sure if it can be done the same in LuxCore

You can buils such texture in Inkscape for example :
multiple-anisotropic-texture-height.resized.png
  • make a document 1024x1024 px
  • add a 1024x1024 circle with radial gradient, repeat : reflected, scale the gradient proportional with ctrl+shift to make the groves smaller (the size you want)
  • create clones to fill the canvas : Edit > Clone > Create tiled clones ("shift" needs to be adjusted)
  • export page as png
To create an irregular one :
multiple-anisotropic-irregular-texture.resized.png
  • same base, scale down the circle
  • fill the canvas with clones of the circle and the pattern you want
  • group the clones, clone the group 3 times offset by 1024 to the right, bottom, right-bottom
  • it should tile..
Using clones allows you to adjust the original circle's gradient to modify all groves width, and in the irregular one, to adjust the "main group" while keeping it tiling.
