OSL Pattern Exploration
OSL is an open shader language that is used for the CPU render engine. The code's flexibility makes the procedural texture have more variability, therefore achieving many effects that standard texture can't.
basic ring osl used with pxr-layer surface
Look-Dev
Basic Look-Dev to combine the OSL pattern with glass materials. Find the OSL code example here.
To make a pattern that works with transparent material, use carefully with a Pxr-layer surface to get the alpha channel. See node below.
Combine circle osl with ring osl to make more interesting shader
Look-Dev
After writing serval OSL patterns, combine them to achieve the more interesting results with the alpha channel.
Create a rectangle or stripe is possibly as well.
Look-Dev
Control the rectangular shape by defining its boundary.

simple Cross osl
Carbon Fiber Shader
For more complicated pattern, define the function at the front of the shader would be necessary
