Graphics Raycaster - Click on overlapped buttons

Questions & Answers
1

So I was playing with the new UI system and I tried one (I know, wierd) situation where two buttons are overlapped, and based on my previous Unity experience, I thought that both buttons would respond to the click (something similar with using the UI on a 3D environment).

Is there any way I can allow this situation? It could come out handy to me when using a tutorial overlay to highlight some buttons.

Its not built into unity. You will have to propagate the click event to overlapped button. Which ofcourse you can do dynamically or used a fixed button as references. Based on how much you are using it.

If your buttons are in different canvas then you will have to disable Graphics Ray caster in one of the canvas to get the button your like to work.
