EZMat has a helper script that will read any existing shader (that is in material room) and output a partial Python plugin that makes the same shader again. This is not the last step. At that point you have to change some of the lines to use parameters, and then you have to set up glue code to copy the parameters from the EZMat ui into the shader.

However - I'm working on a plugin that will make it a one-click to use EZ Mat UI on any of the shaders I made that use Parmatic-style (PM:something) parameter nodes I've been using for years.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
