From within the Material Room, and with BB's shader dsiplayed, run the "EZMat Generator.py" script and save the output somewhere convenient with a .txt extension, so that you can easily load it into your text editor.

The 'Porcelain.txt' file in the tutorial archive is a copy of what you should have ended up with.

This text file contains a load of Python code that we can copy and paste into our plugin code. It basically contains all the commands needed to create the node structure you can see on the screen. In the next post I'll show you where to paste it in ez_Porcelain.py
