Quote - if ((not no_pyd) and dist <= threshold) or (no_pyd and dist <= threshold**2):

back to

if dist <= threshold:<br></br>
as well?

I did.  Yes.  Things are much cleaner than before.  :lol:

:blushing:  Sorry.  I don't want to cut into your time.  I wasn't sure if
you were still working on adjustments to the script.

I'll prep the files and PM you with a link.  You can look at them if you'd
like, but please don't let me drag you away from anything.  You can say no, if
you want.  I wouldn't have asked if I 'd known you'd moved on already. 

The problem definitely isn't due to your grid code.  I'm applying the grid to both
non-pyd and pyd cases now.  It seems to speed up both. 

This is one of the more bizarre errors I've seen crop up since starting with
Python programming.  Huh.  When I've seen similar things in other situations,
it was usually due to some unexpected behind-the-scenes change to data formatting
made by some built-in function of the programming platform.  (I'm looking at you, Numeric....)

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
