White/Black Screen

December 22, 2010 - 4:04am #1


i am new to AR and i have tried to set up a AR test application with Unity and with the AR plugin.

When i build the project and copy and install it on my devise, the application starts normal.
However after the Unity logo I get a white screen. My devise is a HTC Desire.

Changing the Graphics Level from OpenGL ES 1.x to 2.0 changes the screen to black, but still no video stream.

Thank you for the help in advance

Are you using Beta 2 of the QCAR Unity extension? It just came out last week, and is available here:


Make sure that you have updated Unity to version 3.1.

It is important that the ARCamera is the main camera in your scene, so you may have to delete any other camera objects when creating a new AR scene.

Also try running one of the sample applications, such as ImageTargets. Do you get the error with the sample as well?
