Gil, all of the walls of my house are children under an empty game object. In a schematic, I want to change their Cast Shadow to false upon a key press. The thing is that I can't find a way to get all done in makinom. I am able to change them individually using the change field node, but that will take too long, considering I have hundreds of wall pieces. Is there a way to let makinom run through the child objects of the parent and look for their mesh renderers?
