window of the material:

  1. Set Rendering Mode to Transparent or Fade.
  2. Select the Albedo swatch to open the Color window.
  3. Set the Alpha (A) slider. A value of 0 means fully transparent, and a value of 1 means fully opaque.
A range of alpha values from 0 to 1
A range of alpha values from 0 to 1

Use a texture to control transparency

If you use a texture for Albedo instead of a color, by default the alpha channel of the texture controls the transparency of the material. A value of 0 in the alpha channel means fully transparent, and a value of 1 means fully opaque. You can use different values to make different areas more or less transparent.

Unity combines the alpha channel of the texture with the alpha value you set in the Color window. For example, if you set the alpha value in the Color window to 0.1, opaque texture pixelsThe smallest unit in a computer image. Pixel size depends on your screen resolution. Pixel lighting is calculated at every screen pixel. More info

To check the alpha channel of a texture, follow these steps:

  1. Select the texture in the Project windowA window that shows the contents of your Assets folder (Project tab) More info

  2. Go to the texture preview section and select the Alpha (A) button. The preview displays black for 0 and white for 1, with shades of gray between.

The window uses a single texture to create a fully opaque window frame, partially transparent windows, and fully transparent gaps.
