How do I change the texture of a barrier device to the Sky?

When adding a barrier device on none UEFN maps i.e. via Fortnite Creative the barrier device has various options and sky is one of those options (or was when I last checked)…but in UEFN it is red.
I cant seem to figure out how to change it to sky so was hoping people here can help me to sort it.

You can just search for barrier in the Barrier Material option and it will show most of the barriers. Alternatively you can just use launch session and then select a barrier material from the fortnite client

Thanks for the reply,
I have been doing as you suggest by searching for them but there is no option to make the texture of it then to a cloudy sky or … the cyberpunk looking city I cannot remember the name.

Some of those I think don’t have barrier on their name or they aren’t available in the material picker, for those you can just launch a session and manually select them in game
