Title: NGUI Sprites get garbled when used along with the Vuforia AR plugin
Post by: thePostFuturist on January 04, 2015, 08:14:03 PM

Hello,

I'm working with the Vuforia AR plugin, and NGUI Sprites keep getting garbled when used together: alpha channel gone (now black bg), letters in text become rectangles.

I've tried a few things, such as forcing Unity to include the shaders provided by NGUI, to no avail.

Vuforia creators think this might be due to the shaders' render queue: https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/ngui-vuforia

This is something I haven't tested and am not even quite sure how to test.

Last thing: in the attachment screenshot you will see a garbled NGUI Sprite. Underneath it, however, is a texture that Vuforia uses, which preserves its alpha and seems to be unaffected.

Thanks for reading.

I am not familiar with Vuforia. The shaders NGUI uses are very simple. They're basically the same thing as Unlit/Transparent, except with vertex colors. They don't write to depth, but they do use alpha, like all transparent shaders.

Which shader corresponds to a regular UISprite chosen from an atlas?

I should also note that Unity's new nuGUI is unaffected. Both text and graphics render the same.

Depends on the atlas you chose. Select the material used by your atlas and you will know.
