I have built a 2D Scene with a Canvas, filled it with an UI image of background and other UI game objects.
Then I tried to built an Explosion Animation and try to put around the UI game objects on the Canvas. I can see the Animation when I disable the background. I tried to adjust all the z position values, but no way to put the Animation on top of the other UI game objects. While I should keep using the Canvas in Screen Space - Overlay mode.
