UISprites On 3D Objects

[Ferazel]

I'm know that NGUI wasn't designed for it. However, what I'm trying to accomplish is as follows. I'm trying to see if I can put transparent UISprites on 3D objects in the scene. Kind of like symbols on a die. Then have the rendering be correctly determined by their z-depth. Do you have any recommendations?

Right now I'm using Sprite Manager 2 to get the sprites in the scene which works great... because each sprite relies on dynamic batching, but now I need to go those symbols in the UI as well. I'd rather not double-dip on having an atlas for the faces and having those same symbols in the UI texture atlas.

NGUI can handle it just fine. All NGUI widgets are just scripts on game objects somewhere in the world. For your case, you will likely want this kind of a setup:

3D GameObject
- UIPanel and FaceCamera script
--- Scaled Object (something to adjust the scale of your UI element)
----- Widget
----- Widget
----- Widget

I'm fighting this exact issue right now.  What do you mean a scaled object?  I'm fighting scaling issues when attaching to my 3d objects so I'm dying to have some advice on this subject.  Thanks!

By default if you add a UI sprite to an object, it will be in pixels -- so if the sprite is 100x40, it will be 100 by 40 units. If there is no scale, this will result in a huge sprite on top of your regularly sized 3D model.

So what kind of scaled object do you use and how do you do it?  I'm just having a hard time grasping it.  Thanks for your time.

I guess what I'm asking is what UI object should I use for scaling... What is the best object to use?

Thanks!

Eh? o_O

In your case, there is no "UI" per say. You are adding UI elements to existing 3D hierarchy. Your UI elements aren't going to be parented to a UICamera or a UIRoot. In fact, you won't have either of them.
