when my canvas rendermode set to “screen space overlay”,I found the particles can’t see,is there any way to use Particle system under this mode? I know it work in camera Or world mode.
“screen space overlay” by definition means renders last.
As you said “camera overlay” works fine. So why do you not want to use it?
With overlay, it is always drawn last.
If you want particles to appear on top of the Canvas, then change the render mode to SS - Camera and set the plane distance back from the camera. Then you can render particles between the camera and the canvas.
This is annoying. Setting the render mode to SS camera does not work. I want to animate an exp bar in the UI, but I can’t because I can’t tell the particle system that it is part of the overlay. The annoying thing is that it works perfectly fine in the inspector, but not during Play.
