Thank you! This saved me so much frustration. I am having a problem however, similar to Cristian, it works perfectly on the cube but the button does not indicate a hit. I put a box collider on it as described, and also tried a box collider 2D just in case, but neither seem to work. I am using the latest version of Unity and the SteamVR. Do you have a project we can download? That might help.
