I am creating a 2D game (Unity 5.1 @ ). In my scene I have an object with a small point light as attached component. The problem: when I set my background, an opaque texture covering the whole screen, the point light is not visible anymore. When I deactivate the background - the point light is visible again. I think the solution is quite simple, I just don’t find it and I am struggling the whole day with it already… Please, help!
The background picture a child object of a UI Canvas (stretched for main camera, not in overlay mode), the sorting layer is behind every other layer. The object with the point light is at default sorting layer (which is in front of the background layer). Object is visible, but not the light component. What am I missing here?
Not pretty sure, just some guess.
=> Point light is a 3D element, UI Canvas is 2D element.
=> So in common scene, unity will draw 3D mesh first, then draw 2D ui part.
=> Your background is a full screen picture, so maybe the reason is incorrect rendering order between 3d and 2d ?
I have no idea how to edit the “queue” tag, don’t really want to mess with shaders at that low level… Instead I use a work-around with a second camera. Not really awesome, but it does the trick so far…
