How can particles be used in local space?

Thx DK. Would you look at my WAY of local-spacing and check it for stupidity on my part. I’m on thin-ice, here, intelligence-wise. (thx) :slight_smile: Others welcome to proof-read/debug, too, of course.

Want a BUGS report for that, or… want to consider THIS a report, or… am I doing something wrong there? (thx)
