This property determines the transparency of the rendered image. It allows you to change the image transparency without directly modifying the rendered object. A value of 0 is completely opaque, and a value of 1 is completely transparent (invisible). The default transparency is 0.

This property behaves similarly to GuiObject/BackgroundTransparency or BasePart/Transparency except that it is applied to the rendered image.

The image below demonstrates the same ViewportFrame with two different transparency. The first image has a transparency of 0 and the second image has a transparency of 0.5.
