Hi all,

I am just making some simple lighting model shaders.

I have found a way to add OGL preview by adding OGL parameters to the Material Shader Builder through the edit parameter interface, and making references to the relevant properties inside VEX Builder.

This doesn't seem very intuitive, and I wanted to know if there is a better workflow.

There is a file - $HFS/houdini/scripts/shop/shop_oglsurface.py
He's responsible for adding OGL parms automatically. You should copy it to your home scripts dir, and modify it, so the scripts knows, what parms to add and link on your surface shader.
