how to implement canvas in google cardboard?

hello, I tried making canvas in unity for google cardboard. The canvas is not appearing in the google cardboard however it appears in game view in unity. Please help.

thanks in advance.

5.3.4p2, a bug in Unity prevents rendering World Space uGUI Canvases into a RenderTexture.

Hello I found a fix

in your canvas
change Render Mode to-> Screen Space Camera

change Render Camera to → Your camera

change Plane Distance to a very low number but not negative

In the the example scene that comes with the unity cardboard plugin, the canvas is a world space canvas.

That way it lives in the 3D space and can be interacted with normally.
Make sure you have set the Event Camera on the canvas to your MainCamera and add the Physics raycaster Component to the Main Camera.
