I was adding an object with multiple child objects from a different layer. It was working fine in testing, but then I tested it again after making changes and all the objects appeared invisible. This is the same for any added object whether it has child objects or not. I have been unable to get the added objects visible again. Does anyone know why this is happening?
I figured out the problem, somehow every object wanted to add had "Invisible" turned on. I never did this, and I don't know how it was done either.
