Game and scene view okay but upon clicking play, weather setup not visible

I have created a weather system in Javascript. Everything is okay, I have setup the camera. The camera preview and the initial game preview are correct. However, upon clicking the play button, it then reverts to a previous setup, without the clouds and the mountain textures. What should I edit so that it would still be the same upon playing it? I tried to build the game, thinking that maybe there is only a problem in the preview, however, it only showed the latter without clouds.

Hard to figure from a mere description. Is your camera set to depth or skybox or solid color…is the layer culling set up properly…is the clipping range less than the distance from the objects or images in your setup…etc…etc…etc…
