See persistent models in AR

Hi,

I am using Vuforia and Unity to do AR. So far I have gone through the ImageTarget example, and am able to see the teapot using my Samsung Galaxy S4. I've also managed to overlay some UI elements on the screen.

Now, I'm trying to place a persistent 3d object (capsule for example) in the world.

However, when I place a capsule say, next to the teapot, I see only a white screen when I start the android app.

Why is this so? How can I resolve this?

My scene hierachy is like this

• ARCamera

• Directional Light

• ImageTargetChips

• ImageTargetStones

• Canvas <-- for UI overlay

• EventSystem

• Capsule <-- adding this into the world causes screen to turn white

Even if I shift Capsule to under ARCamera, I only see white when I start up the app.

Thanks.
