Using Materials in Unity
Creating Transparent Window Effect in Unity
First step is to create a Material that I can use for the glass and assign it to the GameObject.
I use the Albedo tint color to get the look that I am going for. I changed the alpha value to 47, and change the color to black. notice that I can get some interesting effects by using different colors. A white color gives me a more frosted look.
Glass reflects light and you can things that are in front of the glass like a mirror.To get this effect I have to adjust the Smoothness. The higher the smoothness the more of the environment the object will reflect.
Now I have a window in my scene.
