Worldspace canvas blocking input of Screen Space Overlay Canvas

Questions & Answers
1

I have a worldspace canvas and a SSO canvas. Clicking on a button in the worldspace canvas activates the screen space overlay canvas in the hierarchy. Buttons in the sso canvas don’t work if they are in front of the worldspace canvas.

I have tried switching the places of the canvases in the hierarchy with no change.

I have changed the order in layer values with no change.

Shouldn’t a screen space overlay supersede a worldspace canvas? That would make sense to me.

I had exactly the same issue.

My problem was related to my SSO canvas having custom sprite images which actually blocked the canvas rays from going through to be able to hit the WS Canvas (and button).

See if your SSO canvas has a blocking sprite image…
