FXAA Effect
Deprecated
This legacy effect is deprecated. Use the multisampling, the temporal anti-aliasing or the SMAA of CameraFrame instead. See Migrating to CameraFrame.
Fast Approximate Anti-Aliasing (FXAA) is an anti-aliasing algorithm created by NVIDIA. It provides an easy and fast way to add anti-aliasing to your scene.
