Create second 2D UI or separate widget hierarchy?

[kruncher]

I would like to adopt the following project structure:

GUI Root (used for GUI)
|---> HUD
|---> Main Menu

Scene Root (very basic 2D scene containing 1 background and several static sprites)
|---> Panel
|--------> Background

Where "GUI Root" is saved as a prefab and "Scene Root" is different on a per scene basis. Since this game is for mobile I want to avoid keeping redundant background textures in memory. Usage of NGUI would be useful since UIStretch is needed for the background.

Does anybody have any thoughts as to how I might achieve this?

Just use two UI setups, each on a different layer. I do that in Starlink with the 3D and 2D UIs.

Awesome stuff, thanks! That was the missing link for me using a separate layer!

Btw, your Starlink game is really nice! I am going to get this on iOS. I hope that your sales are going well!

It pays for tea, but that's about it.
