BB, what am I doing wrong? I copy and pasted the matmatic script you gave above into Notepad and saved out as an mm1. I put the file in my MatmaticDemos folder in both Materials and Pose and then I ran the compile script. I got this error message.

verbose 1
Processing script C:Poser ProRuntimeLibrariesposeMatmaticDemosBasicPavement Puddle.mm1 -> pose
MATMATIC Script Error: name 'PM' is not defined
Traceback (most recent call last):

    antigamma = PM(1, "Gamma")
NameError: name 'PM' is not defined

So, what am I doing wrong?
