In 4.22, temporal AA rendering artifacts can be seen on MotionControllerComponent attachments. Other AA methods look to be working without artifacts.


Not seen with Oculus


Workaround: Set "Disable Low Latency Update" on your Motion Controller Components to 'true'

Steps to Reproduce
  1. Create a VR Template project
  2. Set Anti-Aliasing Method in Project Settings to 'Temporal AA'
  3. Play in Editor
  4. Look at palm of hand and move in small, smooth circular motion. (Also highly observable on gridlines of default material with a StaticMesh attached to MotionControllerComponent)

Result: Temporal AA Rendering artifacts visible
