So I tried to add this rain effect on my scene all good until I want to test it. In the scene view the particle effect is visible but when I go in game view there is no effect. This is my particle system:
If I make a new project and I tried to place a particle effect it can be seen on the scene. In my current project I have a canvas with a button on it, I am not sure if this can affect my game.
Animated is an object which have a collider which interact with the particles. Canvas contain a button which trigger an animation for the object from above.
