Hi everyone, I have a Canvas in my scene and If I touch any button, the raycast go through the button and instantiate an object, how can I prevent that? I'm using the HelloARController. Thanks.

I found a solution: add this line: if (!EventSystem.current.IsPointerOverGameObject(touch.fingerId)) before the line: if (Frame.Raycast(touch.position.x, touch.position.y, raycastFilter, out hit)) It worked for me.

Hello , the Frame.Raycast method is used only to detect the Trackables objects of ARCore , it's not used for normal 3D Objects and Canvas. Take a look at the classical method of unity : Physics.Raycast

Hi, thanks for the report and the workaround.

Glad you figured this out.

I'm closing this report as the issues you are describing are general Unity issues and not ARCore specific.
