We are using 5.1 Official as of today but getting dark streaking in VR using Lumen and Nanite which we weren’t seeing in Preview.

Anyone else seeing the same thing?

Hello.
I am also having the same problem.
I have no idea what the cause is.

If you are using Vive Index like me, this solved my issue. In the command prompt while you are playing ( use ~ to bring it up. ) type r.RHIThread.Enable 0

Hope that helps.

We’re aware of this issue and are working to resolve it - I’ll update this thread when it’s fixed. Remember that Lumen/Nanite for VR is still experimental!
