What is the meaning of "TAA Threshold" in Billboard setting?

 

Hello,

As the title, is this something related to Unreal Engine or just for the video input? Need to adjust?

Hello, 

If you place objects in front of the billboard, you have to take some steps to avoid visual artifacts. The reason is that Unreal uses Temporal Anti-Aliasing (TAA) to make the edges of objects look smooth. The problem with TAA is that it makes the billboard look very blurry, so we disable it where the billboard is. By default, TAA will also be disabled for objects that are in front of the billboard. The lack of TAA might make the edge of these objects look jagged. If this happens you can turn TAA back on for these objects. How you do this depends on whether the object is opaque or translucent. These steps have to be done individually for each object that occludes the billboard.

Please read the full guide here for more details:
