I recently made a simple GUI with the new UI system in 4.6 but I have one MAJOR problem. The buttons doesn’t work. I can’t hover over them, click on them or anything like that! If you know what could cause this, please tell me!
For a button to work it needs to be a child of a Canvas that has a Graphic Raycaster Component attached to it.
If there are multiple canvases and more than one have a Raycaster it’s possible for one to block the other in terms of input but not visually, so make sure it’s not under something.
I had a similar issue, where my solution was to change the “Order in layer” for one of my two Canvas from 0 to 1. Before both Canvas order in layer was 0.
