How to fix invisible Teleport Arc in VR when using physically correct lighting

Using the UE5 VR Template project, if I switch the lighting to use physically correct units, the teleporting arc becomes invisible.

Steps:

  • Add a PostProcessVolume, set to infinite extent and clamp exposure (EV100) to say 14.5
  • Set Directional Light intensity to 110000 lux

Now all lights in the scene are dark because their intensity is not specified in physically correct values, this is not a big issue to fix, just go through and update.

My problem is I have no clue how to edit the Teleport Arc to make it visible again… Obviously its brightness is way to low but how to change it?
