Curic Design Option appears to be a great tool!
Particularly for – as Rich suggested – offering design options for clients.
What my tiny texture switcher does is very different. If I have a stage set with a back-projected screen on it, that screen will display different imagery in every scene. The only way I can display that within SU is to have a unique copy of that screen for every scene and toggle visibility.
With this tool you can just assign a new image to every scene. And to the two independent LED walls left and right. I switch the scene, all these images change. Minimal setup, no hidden tags, no duplicate geometry. Just calling one or more image files in your project folder.
Of course you can also change a wall texture, a curtain texture and a floor texture and you have design options, but of course the Curic plugin is specialised for that and a lot more feature-rich, unlike this tiny one-trick-pony. For me that trick is a life-saver.
