Hello Nik_52, Thanks for replying.
From my own understanding, a green spot (i think) is a set of co-ordinates which can be imbedded into poser scene so a prop or a figure can be moved to the location instantly. They are primarilly used in large scenes where using the X-Y-Z co-ordinates take a while for the Actor to get to the pose position.
Many Thanks.
Pat :)
