Inside dopnet, i have 12 object (named as xx_0 , xx_1 … xx_11) connected to merge and then apply position node . I want to access the center position (centroid()) of each of this object at any node position. How can i do this ? trying to do centroid() , but i can't get the path of the object. I tried : centroid(“../position/xx_0”, D_X), but seems this path to xx_0 doesn't exist. Anyone can help ?
