I am trying to find a way to make an eco system stick to an object , for instances ivy on a wall . The eco system painter paints on the wall but how can i make it part of the wall ? At the moment it looks like its on the wall untill i repostion the wall then it leaves the ivy behind. There dosnt seem to be an option to group the wall and the Ivy as one object (at least not that I can see) i am using vue 10 xstream
