Apparently there was a mm1 script that came with it, cobaltdream, that somehow incorporated Parmatic stuff into the shader. I was going to have a look at the script to see if I could see if I could get by this issue:

that I'm having with Parmatic.

My understanding is that the script was included in the pz2 files...

Thanks for that, anyway.
