VRspectator & Lumen?

I’m testing PC-VR & Lumen in 5.1.1 for archviz. It works great already.

Outputting the view on the desktop while in VR using HMD mirror2 gives the ‘audience’ a nice view as well. But, I like to make it a bit more comfortable for the viewers by using the VRspectator and dampen the VRcamera as was shown in a recent Livestream.

Problem is: Lumen doesn’t seem to work for the VRspectator - even when enabling Lumen in the sceneCaptureComponent2D. See pic.

@VictorLerp any suggestion how to make this work or is this something thats not supported for now and I should use lightmaps instead?

From Lumen Technical Details in Unreal Engine | Unreal Engine 5.0 Documentation

  • Lumen does not currently support Scene Captures or Split-screen.
  • Lumen is not compatible with Forward Shading.

The VRSpectator Actor is using a Scene Capture, and as such it’s not currently supported.

Has this been updated at all - would be great to make use of Lumen and Scene captures with VR

Just in case someone needs this feature (just tested in UE 5.8.1):

The vrSpectator works fine with Lumen if you enable Lumen in the post process settings of the SceneCaptureComponent2D of the vrSpectator blueprint. This way you can get a nice 2nd VR view with Lumen with dampened movement (if you edit the BP for that).

The extra Lumen pass will cost quite some fps.
Some fps can be regained by setting the r.screenpercentage to a lower value (for instance 20 or 33). You get a lower visual quality in the headset but the captured view still renders at 100%.
