Invisible Backdrops?

[Atherton]

It's easy enough to create an active object & then tell it to be invisible but is it also some how possible to create a backdrop & tell it to be invisible during play? the only method that I've encountered involves changing the transparency but that also makes them invisible out of play when your constructing a stage.

any help would be appreciated
Thanks

It would be better to use an active object for this type of thing - backdrops are just images that cannot be messed with at all during runtime. You can make more and destroy the ones you made, but that's it.
