Lumen and Nanite in VR

[SaeedSafikhani]

As you probably know, VR will support Lumen and Nanite in the next build of UE5 (probably 5.1).
I just made some videos of these features in source build, which look amazing.

VR [Unreal Engine 5.1]: Nanite (opaque, transparent) and Lumen

Let's challenge my PC!!! Unreal Engine 5.1 VR

Project Chimera: Enabling nanite and lumen in the Unreal Engine 5.1.0

How does it perform? VR needs to maintain consistent framerate to prevent motion sickness. I am having hard time imagining lumen performing well enough in VR to maintain at least 90FPS without dips in non trivial levels

It is not perfect yet but it is acceptable (as under development build)

If you are interested to test it:

UE5 for VR: Nanite [Masked and Opaque], Lumen - YouTube

Unreal Engine 5.2.0 Oculus Quest 2 (via AirLink) If you like to test it (needs Oculus Headset)
Download Link: Download - MEGA

Inputs:
Thumbstick: Movement
Grip: Rotate Sun

Could you share the thumbstick movement? I works fine in 5.0 but then when I move it to 5.1 everything is gone

Lumen and VR really don’t work well. I have so much noisy shadows. Im not sure if its due to Rartracing or what but so far its been a pain

Heading into 2025 soon and even with the new release of 5.5 Nanite/Lumen VR is just not possible. No where 90fps minimum. Maybe when ethe RTX5090s come out we’ll get there.
