Hello

I was wondering if anyone knew where would be a good start to learn about creating custom shaders in Houdini using VOPs. The pre-built SHOPs don't always do the job, and I haven't been able to find any tutorials for this. Any help would be greatly appreciated. Thanks!

The Vex Builder tutorials towards the bottom are the ones you want.
