Turn the alpha all the way up on each game object you want to glow. Turn the alpha down on each object you don’t want to glow. You can do this in the color picker for the materials attached. RGBA, A is for alpha. On the main camera’s option for the Glow Effect script, there should be a “Glow Tint” option, you can change the color and alpha on that as well. Experiment w/ alpha. You also can go to the main camera, and go to the “Camera” component options, and adjust the color and Alpha of the camera’s Background Color as well. Also, to experiment a bit further, you can change an objects specific material to appear as it’s self lit by changing the material’s shader to Self-Illum / Diffuse…
