A UDN licensee has pointed out that they are seeing unresolved Lumen reflection artifacts when they are running their game in split-screen mode. A video of this behavior is found in the Related tab of the ticket. These same artifacts seem to appear on when running the ThirdPerson sample project and spawning a second player using the reproduction steps described earlier. A RenderDoc capture of the bug can be found here: [Link Removed]

Steps to Reproduce
  • Start the blank ThirdPerson test project in PIE
  • Run `debugCreatePlayer 1`
  • Observe green-ish artifacts as the second player spawns in view 1
  • r.lumen.reflections.temporal 0 makes artifacts more consistent
