Simulated masking

[Alan Gray]

I'm trying to simulate masking by putting an "alpha hole" in a texture and the texture to be masked behind the hole. I think the problem I'm having is that the texture to be masked is a dynamic texture and not in an atlas. Everything else is regular atlas textures. The dynamic texture is the Game Center leaderboard photo - so it's dynamically loaded at run-time. I can't seem to get the UITexture to sort in between the other two textures. I have everything offset in Z as well as using the Depth order for the atlas textures. Any advice on how to get this working?


------------------------ <- background texture (UISprite from atlas)
          ------         <- dynamic UITexture
   --------    ----      <- texture with "alpha hole" (UISprite from atlas)

Put the background sprite and the foreground sprite in different UIPanels, or use separate atlases for them.  If they're in the same atlas and panel, they'll be drawn in a single draw call, so everything will either be on top of or behind the dynamic texture as you're seeing.

It's all in a drag-panel - so separate panels would be tough. But I'll try separate atlases - thanks!

Worked like a charm - thanks!
