I agree with you about the usage of pass vs x=1 but I didn't write the original script, Curious Labs did. FYI for all listeners, the reason you have to wrap the Geometry() method with an exception handler is that is doesn't always return a value of 'None' if there is no geometry present. That's a quirk (as opposed to a bug) that CL is aware of and may fix later. For now, it's the only one, besides hand rolled file I/O , that I'm aware of that you really need to wrap with a try. For ScottA - go to http://home.earthlink.net/~redink3d/bulgePropsNormal.py This version works on my machine (WOMM). Beware that it also affects hair. Need to set a conditional for that. Will hopefully post a better looking version with a gui later this week/weekend.
