Found in 4.22 CL# 7053642, 4.23 CL# 8386587, 4.24 CL# 8557439

Steps to Reproduce
  1. Open attached project
  2. Play in Editor
  3. Use WASD to move to where the second player can see player one
  4. Left click to fire the projectile that uses the material billboard
  5. Look away from the projectile

The material billboard will be render incorrectly as soon as player one looks away 

The material would render as expected regardless of if player one can see it.
