Setting up a Material to use Transparency can be accomplished in the following steps. Opacity: Used to define how transparent or opaque (How see-through / Non see-through ) a surface is. Transparency: Used to define if a surface can be seen through. However this is only happening because the Material was setup so that it uses Transparency.Ĭhanging the Opacity on a Material that is not setup for Transparency will have no effect on how see-through that Material is. This makes the Material go from completely transparent, or see-through, to completely opaque, or non see-through. Starting on the left and moving to the right, the Opacity of the Material is increased from 0 to 1. In the image below, we can see this in action. Opacity refers to how see through a surface is while Transparency is used to describe that a surface can be see through. When dealing with Transparency in UE4 you will also hear terms like Opacity being used. Transparency can be used to simulate a variety of different real world surface types.īelow is a list of some of the most common uses for Transparency inside UE4. The areas in the middle have a varying degree of Transparency based on how close to Black or White the pixel in the Texture is.

The Texture is a gradient that goes from Black at the top, or full Transparency, to White at the bottom, or no Transparency. The image above demonstrates how Transparency works in UE4 using a Texture to help define which areas should have Transparency and how transparent these areas should be. Inside UE4, Transparency works by allowing pixels to not be 100% Opaque, or non see-through, but have some varying degree of Transparency, or see-through. Transparency is the term used to describe a surface's ability to block or allow the passage of light.įor example, a brick would be an object that has no Transparency while stained glass would be an object that has Transparency.

In the following How - To, you will learn everything you need to know about how to introduce Transparency to your Materials in Unreal Engine 4. However inside of Unreal Engine 4(UE4), Transparency is used to describe if a surface is see-through or not while Opacity is used to define how see-through the surface is. In the real world, these properties are often referred to as Transparency or Opacity and are often used interchangeably to describe the same thing. When creating certain surface types such as water or glass, you need the ability to make the surface not only see through, but also give the surface a sense of depth and color.
