Backdrop Filter
With version 1.18 Prysm supports the backdrop-filter CSS property. This allows certain elements to filter what is behind them and use the result as a part of their background. The feature is used to create the popular frosted glass effect.
The general details about the feature are given in the Prysm’s documentation. Here we’ll go over Unreal Engine’s integration relating to the feature.
Support in Unreal Engine
In Unreal, the feature is supported only in the case of the Prysm UMG Widget. This is the only case when the Prysm Views are rendered after the 3D scene. This means that the content of the 3D scene that is behind the UI texture can be filtered through the elements that have the backdrop-filter CSS property.
In-world views and HUDs are not supported and for them the elements with
backdrop-filter won’t be rendered properly.
