I have a texture change script that comes up with a menu, however I'd like one that allows me to use a linked prim as a remote control. I am working with some friends who make windows, I have rl photos that go behind their window in rl. So I need a remote control to be somewhere else in a room that can change the texture on the window so they can change their view as and when they please. Does anyone have a script that does this?
