How to adjust the size of canvas

[vgggg]

The default setting is too big for my scene. (I'm using Unity for Oculus VR and set the canvas to world space)

Hi,

Inspect the Canvas and reduce the Rect Transform's Scale X and Y. A good starting point might be 0.05.

There is a VR UI Example on the Dialogue System Extras page. It uses Unity's VR Samples package. You might find it useful.
